1983年4月27日在日本北部,由于异常干旱强风引起很多地区的森林火灾。我国东北和日本北部均在北纬40度以北,是一个天气系统控制的西风带地区,移动性高气压和低气压首先通过我国东北而后到达日本,所以我国东北的现在天气形势就是几天后日本的天气形势。据查对在日本发生森林大火的前几天,我国东北的伊春、牡丹江、松花江等地区、哈尔滨市共计一百多处,(3月下旬一4月26日)也发生了森林和城市火灾,损失严重。因此日本对天气形势的分析方法,观测数据、及天气的发生发展规律,对研究我国东北同期内的火险天气予测予报有重要的参考价值。关于这方面的分析报导将分期刊登。
April 27, 1983 In northern Japan, forest fires in many parts of the country have been caused by unusually strong winds. The northeast of our country and the northern part of Japan are both north of latitude 40 degrees north latitude. It is a weather system-controlled westerly zone. The high and low pressure of mobility firstly passes through the northeast of our country and then to Japan. Therefore, the present weather situation in northeastern China is just a few days later The weather situation. A few days before the forest fire broke out in Japan, there were over 100 Harbin counties in Yichun, Mudanjiang and Songhuajiang areas in northeast China, and forests and cities also occurred in late March and April 26. Fire, serious loss. Therefore, the analysis of weather conditions in Japan, observation data, and the occurrence and development of the law of weather in northeastern China on fire danger weather to be given an important reference value. Analytical reports on this area will be published in installments.
