We are always full of complaint about the weather.."sometime hot...sometime cool"...

Can you answer this question when someone ask you????

What is the difference between weather and climate?


The anwers are:

The air that surrounds us extends upwards as far as 500km. The layer that is closest to us is known as troposphere where the air moves, flows, swirls and continuously redistributes heat and moisture from one place to another. The physical properties of the troposphere (temperature, pressure, humidity, precipitation, sunshine, cloud cover, wind direction and speed) at any spot on the earth are what we call weather.

Climate refer to the average long term weather of an area. It is a region's general pattern of atmospheric or weather conditions, including seasonal variations and weather extremes averaged over a long period.
