Temperature, precipitation, sunshine, cloudiness, pressure, wind velocity, wind direction and humidity are important elements of weather. These elements are variable in both at temporal and spatial scale. The scale of temporal variation varies from very few hours to thousands of years. The inter-annual variations in the climatic phenomena are in most parts of the earth surfaces and experienced almost every year. No two years have the same recording of the elements of weather at a place. However a successive group of years may have similarity in the climatic conditions which may be termed as cool or warm periods and wet or dry periods. Such period of time which is larger than one year but upto 30 years is termed as climatic fluctuation. The deviation from the normal course of climatic conditions exceeding the periods of 30 years is termed as climatic change.
