Meteorology

“Meteorology is the study of envelope of air surrounding the planet and of the phenomenon associated with atmosphere”.
It is derived from the Greek word “meteoron” which means “in the sky” or “high in the sky”.

Climate (Greek Word) is a weather condition over a given region during a longest period.
Climatology: “The study of long-term manifestations of the weather represented by a statistical collection of weather conditions over a specified length of period usually at least a few decades”.
Micro climatology deals with pertinent factors (solar radiation, temperature, wind, vapour pressure, CO2) of the environment in the zone lying between the highest level reached by the plant and the lowest depth to which air penetrates into the soil.

Agrometeorology (abbreviate from Agricultural Meteorology) is the branch of meteorology which investigates the relationship of plants and animals to the physical environment.
The use of science of Meteorology for agriculture is called Agricultural Meteorology.

Atmosphere is the air surrounding the earth.
The atmosphere is a mixture of different gases.
It contains life-giving gases like oxygen for humans and animals and carbon dioxide for plants.
It also contains water vapour and dust particles.
It envelops the earth all round and is held in place by the gravity of the earth.
It helps in stopping the ultraviolet rays harmful to the life and maintains the suitable temperature necessary for life.
Generally, atmosphere extends up to about 1600 km from the earth’s surface. However, 99 % of the total mass of the atmosphere is confined to the height of 32 km from the earth’s surface.
