Abstract

A parameterization of the mechanism of solar activity impact on the Earth’s troposphere developed by the authors is proposed for a model of outgoing longwave radiation, based on the integral transmission function. The PC-index of geomagnetic activity, which was developed to monitor the polar cap magnetic activity and reflects the affect of the interplanetary electric field on the magnetosphere, was used as the indicator of solar activity. Based on data from NCEP/NCAR reanalysis, we calculated. The integrated transmission function and outgoing longwave flux for periods of increased and decreased solar activity. Correlation analysis of the calculated radiation characteristics with temperature in the 925- to 700-hPa layer showed that the inclusion of solar activity leads to higher correlation between the radiation characteristics and temperature. Comparison of the calculation results with temperature changes confirmed that the proposed parameterization can be used to include impacts of solar activity in numerical models with the integral transmission function to calculate outgoing longwave radiation.

太阳活动对传出的红外辐射通量的影响的估算

摘要

作者提出了一个基于积分传递函数的太阳活动对地球对流层影响机制的参数化方法，用于输出长波辐射模型。在PC地磁活动指数被开发用来监测极帽的磁活动，并反映行星际电场对磁层的影响，被用作太阳活动的指标。根据NCEP / NCAR重新分析的数据，我们进行了计算。集成的传输功能和长波通量用于太阳活动增加和减少的时段。925-700hPa层中计算出的辐射特性与温度的相关分析表明，太阳活动的纳入导致辐射特性与温度之间的更高相关性。
