On sunny days, with a sky devoid of any clouds, the vast expanse appears endless in a clear blue hue. So, where have all the clouds gone?
Before these sunny days, there may have been overcast or cloudy days. These clouds either transform into raindrops that fall to the ground or are blown away by strong winds. Another reason is that during sunny days, the weather is typically dry, and the amount of water vapor in the air is very low. Water vapor is the primary ingredient for cloud formation, so on sunny days, there will be either no clouds or very few.
Furthermore, the amount of water vapor also relies on upward air currents that lift it high; when it encounters cold temperatures, it condenses into clouds. However, on these days, the atmospheric pressure is relatively stable, and there are no upward air currents contributing to the phenomenon of the clear blue sky.
