新疆高等级公路沿线灾害性天气及其分布

Distributions of harsh weather climate along high-grade highway in Xinjiang province

为了预防灾害性天气对新疆高等级公路交通安全的影响,以新疆吐鲁番乌鲁木齐大黄山高等级公路和乌鲁木齐奎屯高等级公路沿线自然环境的分析为前提,分析了灾害性天气在其公路沿线的时空分布。结果表明:降雨主要集中在夏季;降雪主要集中在当年的11月中旬至次年的3月中旬之间;雾天在冬、春两季较常见;大风、扬沙和沙尘暴主要出现于春夏两季。

In order to reduce the influence of harsh weather conditions on the traffic safety of highgrade highway in Xinjiang province, based on analysis of the natural environment of the regions along the Turfan-Urwmqi-Dahuangshan high-grade highway and the Urnmqi-Kuitun expressway, the time-space distribution of harash weather in those regions was discussed. The results prove that the rain falls mainly occur in the summer;snow drifts chiefly take place from the middle of November to the middle of Mareh; fog sprays mostly come in the winter and spring; the strong wind grainfall, storm grain drops often appear in the spring and summer. 2 tabs, 8 refs.
