प्रश्न
The Coromandel coast has more rainy months but less rainfall than the Konkan Coast. Why?
Advertisements
उत्तर
Konkan Coast faces on-shore S. W. Monsoons during summer. These moist laden winds give heavy rainfall (more than 300 cm.). But these winds do not give much rainfall on the Coromandel Coast as it lies in the rain shadow of Western Ghats. Coromandel Coast also receives winter rainfall from N. E. monsoons, but on Konkan Coast these winds are off. shore and do not give any rainfall. N. E. Monsoon is a dry wind as it blows from the land. Thus, Coromandel Coast gets rainfall in both the Seasons, but the total blows amount is less than that of Konkan Coast.

In above Table the average mean monthly temperatures and amounts of rainfall of ten representative stations have been given. It is for you to study on your own and convert them into ‘temperature and rainfall’ graphs. A glance at these visual representations will help you to grasp instantly the similarities and differences between them. One such graph (Figure 1) is already prepared for you. See if you can arrive at some broad generalisations about our diverse climatic conditions. 
Re-arrange the ten stations in two different sequences:
(i) According to their distance from the equator.
(ii) According to their altitude above mean sea-level.
