摘要
本文对新加坡1984—1989年5个冬季东北季风期间(12月一次年2月)0000UTC的静力能量铅直廓线分布状态进行分析。结果表明,当新加坡大气柱无潜在不稳定能量时,可以根据饱和总温度廓线在行星边界层顶(950—900hPa)有无逆温层,来预报新加坡地区午后有无海风发生。对海风与盛行风的关系,本文也作了统计分析,并初步探讨了本地区边界层顶饱和总温度廓线逆温层的成因。
The vertical distribution of static energy profile was studied using data collected in Singapore during five NE (northern winter) monsoon seasons (Dec-Feb) from 1984 to 1989. The analysis shows that when there was no latent instability energy in the atmospheric column,the saturated total temperature inversion near the top of the boundary layer (950-900 hPa) can be used to predict the occurrence of afternoon sea-breeze in Singapore.A statistical analysis was also carried out to study the relationship between sea-breeze and the prevailing wind. The possible cause of the saturated total temperature inversion layer was also discussed.
