本文通过分析控制我国天气系统的各种气团活动规律,来研究我国森林火灾发生的季节性规律。我国东半部地区预防森林火灾的季节是随着变性极地气团与副热带太平洋气团在南北移动中,两气团的交绥位置变换时,影响着我国南方、北方的防火季节和森林火灾的出现频率。因此冷暖气团的交绥位置的移动与各地森林火灾的发生时间紧密相关。森林火灾的规律在春季是由南方向北方逐渐移动,秋季则由北方向南方逐渐移动。掌握了这一规律性,可做好中期火险天气预报,提前做好防火预防工作。以达到预防的目的。
In this paper, by analyzing the laws governing various air mass activities of the weather system in our country, we study the seasonal laws of forest fires in our country. The season of forest fire prevention in the eastern half of our country is affected by the changing of the appending positions of the two air masses during the north-south movement of the degenerated polar air masses and the subtropical air masses, affecting the frequency of fire prevention seasons and forest fires in southern and northern China. Therefore, heating and cooling regiment of the transfer position of the transition and the occurrence of forest fire are closely related to the time. The law of forest fires gradually moved from south to north in spring and from north to south in autumn. Mastered this regularity, can do medium-term fire weather forecast, do a good job in advance fire prevention work. To achieve the purpose of prevention.
