Spatial and Temporal Characteristics of Strong Winds in Shandong Province from 2016 to 2021
摘要
Abstract
In this paper,the temporal and spatial characteristics of strong winds in Shandong Province from 2016 to 2021 were investigated by using the hourly wind data observed from 1 886 meteorological stations and the objective reanalysis ERA5 data issued by European centre for medium-range weather forecasts(ECMWF).It is found that annual average of 1 476 stations experienced strong winds for gale force 8 and above in Shandong Province.Strong winds in spring accounted for about 40.1%of the year.Annual average exceeded 1 000 stations around 10:00-17:00 BJT,with the highest frequency of strong winds around 14:00 BJT.The northerly winds accounted for about 79.3%,and their most occurrence direction were in NNW direction.Northern coastal area of Shandong Province was the highest occur-rence frequency regions of strong winds,over 30 occurrences per station.The southern coastal region and the central mountain region of Shandong Province had experienced 10～30 times.There are 14 sta-tions with strong winds for forces 13 and above,and 64 stations for forces 12 and above during 6 years(2016-2021),of which dominated by thunderstorm winds.The maximum wind speed was 39.9 m/s at Zhangqiu Station.The most dominantly strong winds affected by weather systems were caused by ex-plosive cyclone.The distribution of strong winds was related to the moving paths and intensities of low-pressure systems.The upper-level cold vortex was the main influencing weather system for strong winds with thunderstorm,of which under the influence of northeast cold vortex up to 63.6%.Then the second one was affected by the low-trough system.The front and back trough patterns had different in-fluences on severe convective weather in Shandong.关键词
