赤道新加坡地区铅直静力能量廓线的初步研究

A preliminary study of the vertical static energy profiles over the equatorial Singapore region

为了探讨能量天气分析原理能否应用在对流活跃的赤道新加坡地区,本文利用新加坡的高空资料,分析了1984年和1985年的铅直能量廓线。初步结果表明: (1)赤道新加坡地区的大气层结多为具有潜在不稳定能量; (2)可以根据有、无潜在不稳定能量,预报新加坡未来12小时内的天气; (3)赤道新加坡地区的大气柱平均能级和潜热能随着季节变动,极大值出现在季节转换期,极小值分别在东北季风初期和西南季风期。

This paper examines the. usefulness of static energy analysis in the deep-eonvective equatorial Singapore region. Singapore upper air data have been used to study the vertical profiles of energy for 1984 and 1985. Some preliminary results are:(1) Most of the atmospheric stratification over the equatorial Singapore region is found to be associated with the- latent instability energy.(2) The 12 hours' weather forecasting over Singapore can be issued according to the extent, of latent instability energy.(3)The average energy level and latent energy over Singapore vary with seasons, The maxima occurred during transitional periods and minima during SW and early RE monsoon.
