Meteorological vs Astronomical Summer

Meteorological summer and astronomical summer are two different ways of defining the summer season. Meteorological summer is defined by the three warmest months of the year in a particular region, typically June, July, and August in the northern hemisphere and December, January, and February in the southern hemisphere. This definition is based on the annual temperature cycle and is primarily used by meteorologists and climatologists for weather forecasting and climate analysis.

Why Does Fog Appear?

Fog is not just a simple weather phenomenon, it’s a scientific masterpiece. From the scientific point of view, fog is the accumulation of water in the air and the further formation of little condensation products of water vapor. Moreover, the lower the temperature, the more ice crystals are there in the fog instead of water drops.
