冬半年,在东北季风控制期间,福建沿海东北大风频繁,起因复杂,等变压梯度引起大风就是其中之一,特别是在每年5—6月,冷空气的气压梯度较小的情况下,其作用更为突出。这种大风,在日常预报业务中较难掌握,容易造成预报失误。本文从实例出发,讨论等变压梯度对福建沿海大风的影响。 In the winter half year, during the control of the northeast monsoon, frequent winds in the northeastern Fujian coast led to complicated causes such as the gale caused by the variable pressure gradient. Especially in May-June each year, when the pressure gradient of cold air is small, The role is more prominent. This gale, more difficult to grasp in the routine forecast business, can easily lead to forecast errors. In this paper, starting from an example, we discuss the effects of such pressure gradient on the wind gusts in Fujian coastal areas.
