JAKARTA, kilat.com- Sun as the main energy source for the earth, it contributes to the occurrence of day and night on a daily scale, summer and winter on an annual scale, and plays a major role in the movement of air masses in the form of wind, both on a local and global scale.
solar activity effect on climate change. In addition, solar activity can also affect solar radiation, the amount of solar energy reaching the earth, the magnetic field around the earth, and the number of charged particles emitted by the sun, thereby changing the intensity of cosmic rays reaching the earth.
It affects the dynamics of the atmosphere and oceans, as well as the processes of cloud formation and rain.
Launching from Jurnal Frendi US on Thursday (26/5/2022), when the sun’s activity is low or the minimum sunspot (SM), the intensity of cosmic rays is maximum so that the cloud cover becomes maximum. This means that the radiation of solar energy that reaches the earth is minimal.
On the other hand, when the maximum solar activity is EM, the intensity of cosmic rays reaching the lower atmosphere is minimum, cloud cover is minimum, coupled with additional energy from flares when EM occurs, the solar energy radiation reaching the earth’s surface becomes maximum.

Global cloud cover causes a warming effect (greenhouse effect) by 13% but also causes a cooling effect of 20% because it reflects energy radiation directly from the sun.
The amount of solar energy received by the earth is very large, with an average of 6.3. 1020 joules/hour is equivalent to the energy of 40 tropical cyclones or 60 of the energy released in a large earthquake.
However, given the enormous amount of solar energy received by the earth, and strengthened by the dynamics of the earth’s atmosphere and oceans, variations in solar radiation can have a major influence on climate. (nda)
