Chapter 4: Climate Exercise For Doing It Yourself, Exercise solutions [Pages 40 - 41]

For Doing It Yourself | Q 1 | Page 40

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. 

For Doing It Yourself | Q 2 | Page 40

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.

For Doing It Yourself | Q 3 | Page 40

(i) Name two rainiest stations.

(ii) Name two driest stations.

(iii) Two stations with most equable climate.

(iv) Two stations with most extreme climate.

(v) Two stations most influenced by the Arabian branch of southwest monsoons.

(vi) Two stations most influenced by the Bay of Bengal branch of south-west monsoons.

(vii) Two stations influenced by both branches of the south-west monsoons

(viii) Two stations influenced by retreating and north-east monsoons.

(ix) Two stations receiving winter showers from the western disturbances.

(x) The two hottest stations in the months of

(a) February (b) April (c) May (d) June

Exercise | Q 4 | Page 41

Now find out :

(i) Why are Tiruvanantapuram and Shillong rainier in June than in July?

(ii) Why is July rainier in Mumbai than in Tiruvanantapuram?

(iii) Why are south-west monsoons less rainy in Chennai?

(iv) Why is Shillong rainier than Kolkata?

(v) Why is Kolkata rainier in July than in June unlike Shillong which is rainier in June than in July?

(vi) Why does Delhi receive more rain than Jodhpur?

Exercise | Q 5 | Page 41

Now think why

— Tiruvananthapuram has equable climate?

— Chennai has more rains only after the fury of monsoon is over in most parts of the country?

— Jodhpur has a hot desert type of climate?

— Leh has moderate precipitation almost throughout the year?

— While in Delhi and Jodhpur most of the rain is confined to nearly three months, in

Tiruvanantapuram and Shillong it is almost nine months of the year?

In spite of these facts see carefully if there are strong evidences to conclude that the monsoons still provide a very strong framework lending overall climatic unity to the whole country.
