阿尔山地区位于北纬46°10′—47°50′,东经119°34′—120°44′,介于蒙古草原和松嫩平原之间,是嫩江、松花江以及黑龙江上游额尔古纳河的发源地。本区气候属于雪林气候,由于它位于西风带内,故为高低气压活动的区域。春季大陆高压势力减弱,暖区内高温湿度低,少雨常引起大风,极利于火灾的发生和蔓延;春季寒潮也易侵入,并发生一年中最大的、时间持久的大风和沙暴。秋季蒙古高压复现,低压出现的机会相当多,有时也相当强大,但不及春季。
The Arxan region is located between 46 ° 10’-47 ° 50’N and 119 ° 34’-120 ° 44’E, between the Mongolian steppe and the Songnen Plain. It is a part of the Nenjiang River, Songhua River and the Ergun River in the upper Heilongjiang River The birthplace of This area belongs to the snow forest climate climate, because it is located in the westerly zone, it is high and low pressure area. In spring, the high-pressure forces in the mainland weakened, and high-temperature and low-humidity in the warm area were low. Strong winds were often caused by less rain, which was very conducive to the occurrence and spread of fire. Spring cold spells were also easily invaded and the largest and long-lasting winds and sandstorms of the year occurred. The high pressure in the autumn of Mongolia recovers, the chances of low pressure appear quite a lot, and sometimes quite powerful, but not as good as the spring.
