Some terminologies

Weather: the physical state of the atmosphere at a given place and time is referred to as “weather”.

Climate : Climate is defined as the aggregation of atmospheric phenomena as intensity and duration of light, the temperature, the humidity, direction and velocity of wind, the quantity and pattern of precipitation etc. over a relatively long period of time (month, season or year) and large territory (zone, state, country or part of continent) constitute the climate of any place e.g. tropical, subtropical, temperate climate etc.

Macro-climate: It refers to the climate of relatively large part of the earth surface, which is observed and recorded by a network of meteorological stations and forms the basis for the characterization of zonal and regional climates.

Micro-climate: It refers to the weather condition of plant stand or around plant canopy or from the ground surface of the plant stands to the deepest root zone in the soil.

Meteorology: It is a branch of physical science that deals with the study of physical processes in the atmosphere and is influenced by radiation, temperature, humidity and wind movement which are responsible for changing the state of atmosphere.

Agro-meteorology: It is defined as a branch of applied meteorology that investigates the response of living organisms to the change in the physical environment.
