Analysis of Cloud Basement Height and Surface Solar Radiation Characteristics of Chengdu Shuangliu Airport
Cloud basement height is an important macroscopic physical parameter of clouds,and surface solar radiation occupies an important position in the global radiation balance.The quantitative study of cloud basement height and solar radiation is conducive to deepening the understanding of meteorology,and then improving the refined urban weather fore-casting.The comprehensive observation ofcloud basement heightand solar radiation in Chengdu can also strengthen the understanding of cloud conditions and the utilization of solar radiation resources in theChengdu area.Based on the ground-based observation data from September 2021 to February 2023 in the Shuangliu Airport area of Chengdu,thecloud basement height and surface solar radiation characteristics were studied,and the results showed that the cloud basement height in the Shuangliu Airport area of Chengdu was higher in summer and lower and close in autumn and win-ter,and the sky in this area was covered by clouds most of the time,which was similar to the cloud characteristics of other nearby areas.Due to the cloud cover,the solar radiation data in the region are generally low,with the total solar radiation being higher in summer,about 540 W/m2,and lower in autumn and winter,with an average of less than 340 W/m2.The diurnal trend of total solar radiation in the four seasons was similar,reaching the highest point from 12:00 to 14:00,and the direct radiation was lower than the scattered radiation in all seasons.This study has acertain reference value in evaluating and predicting cloud characteristics and solar radiation resources in Chengdu.
