Abstract :
One problem under study nowadays is to connect solar activity with meteorological processes in the troposphere. However, at present, there is no model which explains all problems of solar terrestrial links. Investigation of the influence of variations in solar and cosmic rays on conditions in the lower and middle atmosphere plays a significant role in determining parameters of this model. Experimental measurements of the lower and middle atmosphere temperature profile show that it was changed after strong solar flares. A theoretical model explains this phenomenon using an atmospheric absorbent or reflective layer, with heights from 5 to 20 km. Good agreement between experimental data and numerical simulation was achieved for layers of 14-16 and 8-9 km height, respectively, and a coefficient of transparency of about 90%.
