What's the weather like on the Qinghai-Tibet line from September 8 to 10?

I just wanted to copy the climate article, but I copied it all. I hope LZ won't be wordy.

"One Road" Riding in Tibet is certainly the way to go. The standard view is that there are four highways: Qinghai-Tibet, Sichuan-Tibet, Yunnan-Tibet and Xinjiang-Tibet. In fact, the end of Yunnan and Tibet is halfway between Sichuan and Tibet. Therefore, the general routes for riding Tibet are Qinghai-Tibet, Sichuan-Tibet and Xinjiang-Tibet. There are only three modes of travel in the first half of Sichuan and Tibet (plus the northern line of Sichuan and Tibet). Recently, the ancient road between Yushu in Qinghai and Qamdo in Tibet has been easy to walk again. So there is a fourth choice: Kangzang (Tang-Fan Ancient Road). The Qinghai-Tibet Highway is divided into two sections: Xining-Golmud-Lhasa. Xining-Golmud section reaches Chaka via Sun Moon Mountain, Qinghai Lake and Rubber Mountain, and Chaka-Golmud is divided into north and south roads. The northern line is in the northern margin of Qaidam Basin, and the distance is about 140km longer than the southern line. Passing through Wulan, Delingha, Dachaidan and Xitieshan. The southern line runs through the central part of Qaidam basin, and the current road conditions are excellent. The route is Wangga Xiushan, Tuotu Mountain and Xiangride, with a distance of 780 kilometers. Golmud went to Lhasa via Nachitai, Xidatan, Kunlun Mountain, Freezing Spring, Wudaoliang, Fenghuoshan, Erdaogou, Tuotuo River, Yanshiping, Tanggula Mountain, Amdo, Shengli Gongshan, Naqu, Dangxiong, Nyainqentanglha Mountain and Yangbajing. The distance is1160km. Qinghai-Tibet Highway is a national secondary highway trunk line, with subgrade width10m and gradient less than 7%. -.-Xining 0 2200 Huangyuan 45 45 2600 small uphill, with road signs from 109-2000 to 109-2020, suitable for taking photos.

It's a long way after entering the city. -The northern line passes through Ganzi, Dege, Qamdo and Bangda. The southern line passes through Ya 'an, Litang, Batang and Mangkang to Bangda. Then go to Lhasa via Basu, Bomi and Linzhi. The total length of the northern line is 24 10/0km, and the total length of the southern line is 2150km. The altitude difference along the Sichuan-Tibet Highway is the biggest, and there are almost no smooth roads along the whole line. The road is rugged. July and August are rainy seasons every year, and there are often landslides, landslides and mudslides. The starting point of the New Tibet Highway is Yecheng, Xinjiang. The total length is 2840 kilometers. It is the road with the highest altitude. Arrive in Lhasa via Jieshan Daban, Doma, Shiquanhe, Geji, Gaize, Dongcuo, Tsuole, Laga, Lasze, Shigatse and Gyangze. **************************************************************************************

Theoretically, May and June is the best time to ride Tibet every year. Mainly because of the lack of rain. In fact, cyclists usually take vacations in July and August. It is inevitable that there will be some dripping pain. 1, the wind friends agree that uphill is not terrible, and headwind is the most deadly. Because going uphill is like saving money, you can borrow it and pay it back. No matter how many slopes there are, there will always be downhill. Against the wind, you will be in trouble, just like losing money, how much you lose. It's not happy to think about it. In the Qaidam basin, sometimes you will encounter a great headwind, just like a fine, which is extremely depressing. The wind is pleasant, just like winning the lottery. It's really Swan. -Cool. Everyone knows that a cold will kill people. Then you'd better not get caught in the rain. It also depends on luck. A partner caught a cold, had a fever and had diarrhea all the way. Not dead either. Rain is inevitable, but it is more or less a problem. There were all kinds of rains along the way. There is more rain in the section from Xining to Golmud. It's raining in Mao Mao on Rubber Mountain. Smoke is like fog, and it is all wet before you know it. A rash rain fell in the Gobi desert. It turns out that the blue sky and white clouds are shining brightly. Suddenly, huge raindrops fell in a gray cloud overhead, hitting the top of the head, making people jump up, falling three or five points and disappearing. It was raining cats and dogs in Dachaidan, and the earth shook and shook, which was thrilling. It can come to a screeching halt, and then the sun will come out immediately. The air on the plateau is very clear, you can see clouds in the distance, and there are oblique foggy things floating below, which are also rain. Clouds go with the wind, and the rain moves with them. When you're lucky. Yu Yun always jogs a few kilometers in front of the highway, and he is always in a good mood all the way. Or keep following for a few kilometers, then you can't help but drive all the way. Worst of all, people are always in the rain, in the clouds, walking in the rain, stopping raining and staying overhead. Had to running all the way. FT2DS. Usually, if you see clouds in the sky, if they look like a big, thin feather. There may be a thunderstorm. If you see "white clouds floating in the blue sky", every white cloud is round. When there is wind, it will gather into large dark clouds, and there will be rain. The worst thing about cycling in the rain is that the shoes get wet. Cold feet are easy to catch a cold. Secondly, there is water in the crotch, which seriously affects the pedaling action of cycling. Besides, it looks ... awkward. There is a lot of thunder on the road of thunder. I am in awe. In fact, the probability of being struck by lightning is very small. But once it happens, it will be terrible. And traditionally, people who do bad things in secret will be struck by lightning. So once struck by lightning, the whole family will lose face. If you really want to do something, it is to ride a bike and pray sincerely. Or, like me, risk being washed away by the flood and hide in the culvert under the road. Although I know that the probability of being washed away by flood is far greater than that of being washed away by lightning. I don't know if it's stupid or careless, but maybe it's lack of oxygen in the brain. Fortunately, I haven't heard that my brother riding Tibet was struck by lightning. 4, snowy summer is summer after all, and there are not many opportunities to encounter snow. Most of the time, I see the snow on the snowy mountain from a distance. We only had snow at the zero distance of Little Tanggula Pass. However, I heard that on the second day after we passed the Tanggula Pass, a foot of snow fell there. (unconfirmed) 5. The fog is dry in the west, and I seldom encounter fog, but I have encountered heavy fog when I passed by Rubber Mountain twice. I don't know if it's the local climate or coincidence. 6. The flood was originally thought to be a specialty of the south, but it happened in Qinghai. It really happened in front of my eyes and the scenery was spectacular. I thought the flood rose from small to large, from low to high. What I saw was not. It's sunny, ie it has been raining for the past few days. When we left Delingha and were about to reach Tara outside, the flood roared and rumbled across the dry Gobi river bed. The road dozens of meters ahead sweeps like a wall. The water head is more than one meter high. If you happen to ride a bike there, you will definitely wash it away. Although the head is big, the flow is average. When the water level drops rapidly, the road water flow will soon be lower than the central axis. Because I have no experience, I want to pass quickly when I pass by. Causes the front wheel to throw mud and pollute the chain and transmission. It's terrible. 7. There were many hailstorms on the hail road, but they didn't last long. I played table tennis with my helmet, and I was hit by my ear once, which was very painful. 8. Freezing rain may not be common anywhere. We met it at Kunlun Mountain Pass. Not much, just a little symbolic. 9. The dusty Qinghai-Tibet Highway is very long and its geological structure is unstable, so it is necessary to build a railway. So I'm afraid this road will never end. If it is repaired, it will be broken, and if it is broken, it will be repaired. So there will always be dusty roads. And it is extremely fine dust. Stick to chains, luggage, face, handlebars, lenses and alveoli. Dust turns into mud when it meets rain. The abnormal dust in that abnormal place met with abnormal rain and produced abnormal mud. Sometimes it's sticky, abnormal, and you can't step on the motor car. Sometimes it is slippery and abnormal, and the wheels are idling. It's hard and sharp when it's cold and frozen in the morning, and it can puncture a tire. 10, with the most severe sun exposure at the end. The first time I saw the sun, it would make my skin blister. It's true. The accomplice's ears are completely like blisters scalded by boiling water. It's just a day in the sun! Most people will pay attention to sun protection. The tip of the nose, the back of the hand, thighs, ears and neck are generally ignored. I saw the practical application of solar cookers for the first time. A basin of cold water boiled quickly under the illumination of two mirrors. Solar cookers are made in Jiangsu, but I haven't seen them in Jiangsu. **************************************************************************************

"III. Equipment" 1, automobile. For the Qinghai-Tibet highway, because most of them are flat roads. Therefore, it is more appropriate to use a 700C station wagon. Thick models such as 38, 4 1 43 can choose to put luggage. At present, the domestic available models are: Giant -ARK, ROCKMACHINE-CROSSWAY, GT-NOMAD, GT-Timberline (26 ") and so on. The giant ark is relatively easy to buy. It is emphasized that Giant Ark is a product of Giant (Kunshan) Company. Market price ￥ 1698, issued at the end of June 2002. It is a specially designed long-distance station wagon. The specific configuration is as follows: frame: GIANT (trademark) -SUPERLIGHT (ultra-light) -ALUXX (certain aluminum) bowl cover: VP (Taiwan Province province) front fork: RST-TR-PRO-HL(700C) (Taiwan Province province) handlebar: zoom aluminum, angle adjustable horizontal handlebar: zoom aluminum, butterfly handlebar cover: black sponge seat bag. Black rubber strip wheel rim: single-layer aluminum spokes: S stainless steel axle; JOY (Taiwan Province Province) brake: promax-TX 103-V4 brake handle: EF33 (Japan) variable speed dial; EF33 (Japan) inner and outer lines; Ominous pedal: VP plastic type (Taiwan Province Province) toothed plate OTEK HS DK- 15 central axis; Ominous chain: Z(KMC) flywheel; Shimano MF-HG37 rear transmission: ACERA (Malaysia) front transmission; ACERA (Japan) Headlights: I have used Sanyo, and I feel that its advantages are: (1) authentic name. The ark is the ark, bearing everything and riding the wind and waves. (2) the color is resistant to dirt. The same color as dust. (3) Variable speed in mountainous areas. Use ACERA series transmission. There is enough climbing speed ratio. (4) Butterfly handlebars. Different grip postures can be changed to reduce fatigue. (5) The accessories are complete. Comprises a shelf, a grinding lamp, a baffle, a chain box and a tripod. (6) Easy to adjust. The adjustable range of the valve stem is very large. It is convenient to find a suitable riding posture. (7) Sit on the pipe for shock absorption. Reduce fatigue and reduce the probability of "accidents". The seats are very comfortable. I mean, this car seat suits me very well. Not necessarily for you! ! ! (9) The frame is firm. Moreover, the shift line and the rear brake line are all hidden designs. It is not easy to get into water and stick to mud. All kinds of temporary luggage can be tied to the shelf of the car smoothly. Will not affect the normal operation of the rear brake and derailleur. (10) The tire is suitable. It's 700X4 1C, with circular cross section and sword pattern. Lighter on a flat road. Occasionally encounter bad roads, etc. When I bought a car, I made some upgrades to the original car: ALIVIO flower drum, DEORE chain shifter, big board, manual dial, SRAM7.0 flywheel, Z9000 chain, and the use of the original parts is unknown. But compare the corresponding parts of friends at other levels. I think as long as it is used correctly and maintained properly. Original car accessories are competent. Its disadvantage is that (1) foot brace (vertical brace) can only work when there is no load. Once the backpack is installed, the tripod is completely useless. (2) The color matching of the transmission system is not good. I changed the big board and the back dial of DEORE, and the colors are much more harmonious. 2. Carry a bag. Many friends have to use backpacks, handbags and other equipment based on cost considerations. Anyway, you must be prepared for rain. Binding should be as strong as possible, easy to disassemble. It is recommended to choose a backpack for bicycles as much as possible. There are two ways to fix the bicycle backpack: soft and hard. Rigid fixation is firm, and disassembly is very convenient. The disadvantage is that once it is damaged, it is difficult to maintain. Soft type is just the opposite of hard type. But anyway, it's better than tying your backpack to a shelf. As for riding a bike with a backpack ..... you can dream on. You will be laughed at by the old bird. I use VAUDE's three-piece backpack and yellow-green rain cover, which can really resist heavy rain. It is also equipped with an Allen wrench. The hard fixed hook can be adjusted to suit all kinds of shelves. This backpack has reflective patterns on the body and rain cover, which is more practical. 420 3. Auxiliary package. It is very convenient to install a small auxiliary bag in the front of the car or in the middle of the tripod. You can put some snacks and cameras. There are also maps, glasses, pencils and other common items. Unfortunately, I just found out now. I didn't understand. 4.ID package. Special ID bags can be bought in the market. Hanging around the neck. Used to put the address book (this is the most important), ID card, border card, student ID card, and life-saving travel expenses. Bank card or passbook can't be put here. I can't let my ID card touch these things. Unfortunately, I just found out now. I didn't understand. 5. Repair tools. Glue, patch, leather file and pump for tire repair are the most basic things. If the car is a quick-release hub (that is, an axle). The fastening handle can be used to pry the tire. Otherwise, a suitable tire pry bar should be prepared. I only had two abortions. Two spare inner tubes have become the eternal weight in my heart. No one needs two spare inner tubes unless they are extremely unlucky. So one is enough. As for tires, it's hard to say. Flip a coin to decide. Some newer models usually use hexagon screws for various fasteners. Therefore, it is best to bring the appropriate Allen wrench. If it is an old bicycle, you may need a adjustable wrench and a screwdriver. This is heavier and bigger, and you need to decide your choice according to your car condition and physical strength. Other things, such as chain plates, brake lines, speed change lines, pedals, etc. , should be forgotten. Among them, the Sichuan-Tibet line has a steep slope, and some friends may need to reverse the brake pads, which will really break the spokes, but not much. Spare spokes can be used. But thin steel wires as strong and elastic as spokes can have many other uses. It is recommended to bring five. If someone is as neat as me, they need a rag to clean the car. It also has many uses. In addition, nylon tape for electrical installation is also very useful, or ordinary adhesive tape will do. There is also a white nylon belt with a length of 100mm and a cross section of 2mm square, which is used by the railway department to hang labels. There is a small hole at one end. The first group and the last group can be locked. This is a very reliable bag. Combined with the following table: (0) air pump (required) (1) glue (required) (2) patch (required) (3) leather file (required) (4) inner tube (required) (5) spokes (required) (6) adhesive tape (required) (7) Allen key. Some predecessors' articles about clothes have been overwhelming. I won't say anything. I just want to add a little bit about my riding experience. (1) Clothes and pants that can keep out the rain must be available. Cheap raincoats and rain pants are also useful. (2) Clothes with zippers under their arms are very easy to use. (3) Clothes with cuffs that can be easily opened and closed are easy to use. (4) Zippers are better than buttons. (5) Red and yellow with striking colors can improve safety. (6) Shoes should not be overweight. Ventilation and drainage are more important than waterproofing. (7) Windproof and rainproof foot covers are best matched with light running shoes with many meshes. (8) Slippers are necessary, the lighter the better. (9) A headscarf is a must. I bought 2-foot sheets in Xining, which is enough for three people. Looks like Arafat. Gloves are necessary. When we set out, everyone's gloves were colorful. Later, almost all of them used 2 yuan's white gloves. (b) A towel is necessary, and it is best to choose a gray one, because: -) (c) A toothbrush is necessary. Let me think about it. I have used it several times. 1...2...3...(d) Toothpaste is a necessity. In fact, toothpaste can also be used for washing hands and fruits. The effect is still very good. (e) socks are necessary and cotton socks are comfortable but not easy to dry. I prefer thin nylon stockings. It dries easily. (f) The mask is necessary, which saved the brothers' small lungs that were on the verge of failure. It is enough to bring him three. Can also be used as gauze, bandages, towels, rags, toilet paper (? ) sunglasses? Something is better than nothing. Color and depth are not important. Polarization is more fun. I've always thought that the black eyes of orientals can tolerate a little glare more than the blue eyes. That's why I said that the depth of the lens color is not important. Completely personal hypothesis, no scientific basis found! (h) helmet, just so-so. I don't know how to evaluate. When you die, change to a vegetative state. It's time to be in a vegetative state and be seriously injured. When it comes to serious injuries, it will be changed to minor injuries. When it comes to minor injuries, it is changed to fright. This is the equipment I take with me when I travel by bike, but I hope it will never work. It seems to have stopped hail several times. 7. Choose drugs according to your own situation. My list is (1) Band-Aid (40) (also used as adhesive tape, 20 tablets is enough) (2) 2 rolls of gauze (diameter 15 mm, but fortunately 50 mm long is useless) (3) a bottle of Jin Shikang (I don't know if 30 tablets are useful after eating) (4) Ginseng buccal tablets. Or two big western biscuits. Unfortunately, the heat is low. I like to drink Jianlibao all the way, and the price is acceptable. 9. Other (1)GPS seems to have little effect. There are few forks in the road. Seldom use maps. (2) Swiss army knife, this is a good thing, but I have never used it once, I am stupid. (3) Kettle, it is quite practical to put a plastic kettle that can be pulled out on the frame. I still have a big Jianlibao bottle tied to the beam of my car. It's basically enough. If you have an aluminum kettle, you can fill it with boiling water when you eat in a restaurant. Too bad I didn't. (4) Rope, I bought 10 meter 7mm diameter twisted nylon rope in Xining for 2 yuan. It has played a very good role many times. If there is a professional rope, it may be lighter and better to use. Let's choose according to our own situation. (5) Rain-proof cloth or thick plastic cloth. It can be used for grassland corruption and shelter from wind and rain. (6) Sleeping bags, just a little thinner, are mainly used to rest between the body and the hotel's fragrant slate quilt. (7) camping equipment, there are enough hotels on the road, no camping. If you like this kind of fun, it is suggested that Campland-LD 150 be built by one person, which is wind-proof and rain-proof, small in size and light in weight, but unfortunately not spacious enough. Since camping, you need a damp-proof mat. Sleeping bags also need to be thicker.
