solar zenith angle
解釋
太陽天頂角-
A two stream model has been used to calculate the variation of optical depth and their effects to ultraviolet radiation of each extinction material. with the model, the relation among season, solar zenith angle and ultraviolet radiation has been discussed, and the variation of ultraviolet radiation under different clouds has also been studied. the comparative research of ultraviolet radiation among kunming, beijing and other abroad area at the same latitude has also been done
在已建立的計算昆明紫外輻射兩流模式改進的基礎上，進一步計算並討論了： 1各種消光物質的光學厚度變化規律及其對紫外輻射的影響2季節變化及太陽天頂角變化與紫外輻射的關系3不同雲的光學厚度下紫外輻射的變化4昆明與北京兩地模式計算結果比較，以及與國外相近緯度觀測結果進行了比較。 -
In this paper, the solar and land - atmosphere radiation rates are calculated by modtran3 model and satellite observation as well as surface data, solar direct irradiance infrared irradiance solar heating rate and infrared cooling rate were calculated from 43 samples of sunshine day and 5 samples of cloudy day 3 samples of rainy day of different latitudes in 12 stations. the paper analyzed solar heating rate and infrared cooling rate in sunshine day, the factors such as zenith angle, water vapor and latitude were found out correlating with solar heating rate and infrared cooling rate. solar heating rate and infrared cooling rate change on the same day and at the same station
在對晴空大氣的計算中，本文對太陽的直接輻射與地氣系統的紅外輻射狀況進行了分析，並討論在不同的大氣狀況下太陽加熱率和紅外冷卻率的情況，找出與太陽加熱率和紅外冷卻率變化相關較大的因子?太陽天頂角和水汽條件、緯度；本文還進一步分析了不同緯度樣本的太陽加熱率與紅外冷卻率日變化及有雲、有雨情況下太陽加熱率和紅外冷卻率的變化情況：另外，文中通過改變二氧化碳在大氣中含量的方法，討論了它對太陽加熱率與紅外冷卻率的影響。
