摘　　要：利用常规气象资料分析了呼伦贝尔市2021年3月15日一次明显的大风天气过程,结果表明:高空深厚的强冷空气为大风提供了背景条件,地面强的锋区和密集的气压梯度为大风提供了动力条件,次级环流加强动量下传作用,提高了地面风速。Using conventional meteorological data, this paper analyzes an obvious gale weather process in Hulunbuir on March 15, 2021. The results show that the deep strong cold air in the upper air provides the background conditions for the gale. The strong frontal area on the ground and dense pressure gradient provide dynamic conditions for strong winds. The secondary circulation strengthens the momentum downward transfer and increases the ground wind speed.
