Weather forecast There are two ways for weather forcasting: Short-range forecasting Meteorologists can make somewhat longer-term forecasts (those for 6, 12, 24, or even 48 hours) with considerable skill because they are able to measure and predict atmospheric conditions for large areas by computer. Using models that apply their accumulated expert knowledge quickly, accurately, and … Read more

Distribution of rainfall in India India has a monsoon type of Climate. Rainfall occurs only for about three to four months and is uneven, unreliable and erratic in nature. Rainy season in India extends from June to mid- September. Sometimes at the time of arrival, the rainfall pours heavily which is commonly known as the … Read more
Classcial Theories: Halley’s Thermal concept: Indian monsoon is because of contrast between Indian Subcontinent and adjoining Indian Ocean. Halley’s theory, suggested in 1686, considers the summer monsoon to be a regional phenomenon. Aerological concept: This was suggested by R. Scherhag in 1948. According to this theory, monsoon circulation develops due to changes in air … Read more

Variable Climatic condition throughout the state has led to the development of different agricultural practices. Scientists have divided the state into following agro-climatic regions:- Western Agricultural Region:- It covers the sandy arid plains with low rainfall and thus about 70% of the net cropped area is under Kharif Crops of bajra and pulses. … Read more
