Meaning and definition of weather

“Weather” is an average condition of atmospheric constituents or elements of a particular place in a day. As per the meaning and definition of weather, it is a temporary system of atmospheric elements originated in a place over a short period of time. So, it is subject to change with change in time and place such as hot and sultry noon, bright and sunny morning etc.

“Elements of weather”

As I stated earlier that weather is an atmospheric phenomenon originated from the sequential pattern of different elements like, temperature, humidity, wind, sunlight, rain etc. It is subject to change according to the change in the order of respective elements. So, let’s see the major elements of weather.


Temperature is a master factor, as well as major elements of weather. It is also a major determinants of humidity, pressure, and wind system. For definition, it is just degree of hotness or coolness. Whenever the degree of temperature rise or fall, the other elements are also subject to change in the same manner. Thermometer instrument is preferred to measure the rise and fall of degree.


You might have read or listened about the low and high pressure atmospheric conditions. It is made up of atmospheric gases which have certain weight. Due to this weight, it exerts pressure on the surface of the earth in accordance with weight and surface area. Pressure is instrumental in formation of pressure gradient, wind system, temperature inversion, and adiabatic phenomenon. It is measured in the barometer instrument.


Rainfall is a product of certain complex mechanism that range from evaporation, cloud formation to condensation and rain formation. There are different forms and types of rain or rainfall. It may be drizzle, snowfall or hailstorm. On the basis of origin, it can be c as Orographic, frontal, and convectional rainfall. Rain gauge instrument is used to measure the degree of rain.


Humidity is another important element which is instrumental in the formation of convection currents and clouds. It incorporates a lot of latent heat from atmosphere and get released at the time of condensation. On the basis of water vapor content in the air, humidity is classified as relative, absolute, and specific humidity. Hygrometer is used to measure the humidity in the atmosphere.

Apart from this, “winds, clouds, and sunshine” are other elements that play greater role in the formation of weather system.
