Weather can be defined as the physical condition or state of the atmosphere at a particular time and place. Most weather happen the part of the earth’s surface called the troposphere
Climate is defined as generalized or average condition of weather of a place or region. the average of weather condition is taken over a long period not less than 30 years of time to establish the climate of the place.
It is a composite or generalized of the variety of day to day weather conditions.
Difference between weather and climate
|1||Instantaneous physical state of atmosphere at particular place and time||Normal physical state or generated condition of atmosphere or long term average condition of a place. the period over which the climate is determined is at least 30 years|
|2||Weather changes refer to specific instant of time( day or week). weather changes can occur wthin short period of time that is from one minute to another or within an hour||It is generalized over a longer span of time and for a longer area. climate change occurs slowly over years and can have detrimental impact on both environment and economic activities. for example the recent increase in temperature have led to the melting of ice caps leading to increase in the sea level|
|3||It is expressed in terms of numerical values of meteorological elements.||It is expressed in terms of time averages and area averages of meteorological elements.|
|4||Weather is measured in observatory. So the observatory must at a place for which weather is to be described.||This is derived information on regional basis. So scripts of observatories extending over a region are necessary.|
|5||No statistical treatment is applied to the meteorological elements. They are used as observed and hence always changing.||Application of statistical method over a longer period I done. It is more or less stable with few random changes.|
|6||it provides meteorological information.||It constitutes geographical information in respect of weather.|
|7||Weather of two places having same numerical value must be the same.||Climate of the two places having the same averages of weather can not be same, because their distribution over the years may be different.|
|8||Weather can be categorized as fair, unfair, excellent etc.||Climate is classified as desert climate, marine climate, tropical climate etc.|
|9||Weather decides the success or failure of a crop in a particular season.||Climate decides the type of crop suitable for a region, while introducing new crops climate is considered.|
|10||Adverse weather results into crop failure or loss and warrants short term contingent planning.||Climate is considered in long terms agricultural planning.|
