Even in the rainy season to Tibet tourism, the day unprepared rain gear, and never will in rain, and the evening go out, is to be careful, when night is a feature of the Tibetan climate. Tibet from SiWuYue rainy season by CangDong rule was, take off the southern ink began, rainfall center XiYi constantly, and gradually expand to Lhasa and xigaze, the centre zone, to July throughout Tibet into the rainy season, the late September to early October, the rainy season will soon end.
All over the Tibet rain rate (that is, from the morning to the evening at 8 at 8, the precipitation of 24 hours a day percentage precipitation) are 60% or more, especially in the yarlung zangbo river valley night is the most significant, and the rain in Lhasa rate 85%, xigaze is 82%. Only the southeast and the Himalayan region of Tibet, night less, about 50% or so.
In Lhasa in rainy season, every day at 12:00 noon to afternoon 3 when, almost no rain. A until the evening, the clouds rise everywhere, the dark clouds covered the stars just revealed gradually, soon it rains. 2 before and after midnight when, the lightning and thunder hail and thundering, also reached the highest rainfall. To the east to white, the rain showers and the rain gradually decrease. The morning cloud that open the rain jehiel, and a cool and refreshing, around noon, the sky was miles, scorching sun. As the sun goes down to the west, the clouds and up, night repeat process, the rainy season almost every day.
The formation of Tibet night, except by the big range weather situation outside influence, mainly by the local terrain conditions caused by impact. During the day the sun radiation hillside strong, heated area is big, raising temperature quickly, formation depression area, valley heated area small, raising temperature is relatively slow, the trip GaoQiYaOu, air GuFeng rise from valley form, formed in the sky one top convex, flat bottom, form if cumulus clouds billow of steamed bread. But during the day the sun radiation is strong, the clouds of water droplets evaporate to dissipate heat absorption, so the clouds become thinner, and even the sky cloud or less clear. And when the sun set, the ground cooling fast, hillside cooling fast, cold air sinking and uplifting valley warm wet air, increased the atmosphere of disturbance, provide the conditions for rainfall. Plus night genting cooling fast, the warm, convection strengthened, and the clouds in increasing stability, water vapor condensed to saturation, and finally form the night.
