武汉军运会历史同期气温特征分析

Analysis on the Characteristics of Temperature in the Same Period in the History of the Wuhan Military Games

摘要: 应用武汉市5个国家气象观测站有观测记录以来的气温资料，从历年、常年和近年气温背景入手，分析了军运会所在10月和会期18~27日的平均气温、平均最高、最低气温以及极端高、低温时空特征，同时对军运会期间气温日变化以及开闭幕式晚会时段的气温作了简单，并分析了极端气温出现的天气形势。结果表明：武汉气温总体呈上升趋势，空间分布南高北低。武汉军运会同期，武汉市气温具备典型的秋季气温变化特征，10月处于一年中气温下降阶段，逐旬气温呈稳定下降趋势，下旬气温下降明显，气温日变化显著，气温日较差平均8℃左右。开闭幕式晚会时段气温适宜，军运会历史同期出现了30℃以上极端高温和10℃以下极端低温，具有时空分布不均的特点。

Abstract: Based on the temperature data from 5 national meteorological observatories in Wuhan since the observation started, and the background of the temperature in the past, perennial and recent years, we analyzed the average temperature, average high and low temperature, daily temperature changes, and the temporal and spatial characteristics of extremely high and low temperatures in October during the 7th CISM Military World Games. At the same time, we briefly analyzed the tem-perature during the opening and closing ceremonies, and the weather when extreme temperature occurred. The results show that the temperature in Wuhan in that period was on the rise in general, and the spatial distribution is high in the south and low in the north. During autumn in the past time, the temperature in Wuhan has a typical change. The temperature shows a steady decline from ten days to ten days in October, and it drops significantly in the last ten days of October. The daily temperature varies significantly as well. The daily temperature gap is around 8˚C. The temperature during the opening and closing ceremonies was suitable. But there were extremely high temperatures above 30˚C and extremely low temperatures below 10°C, which were characterized by uneven temporal and spatial distribution.
