Topic: Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc., geographical features and their location- changes in critical geographical features (including waterbodies and ice-caps) and in flora and fauna and the effects of such changes.
1) Arabian Sea is comparatively less prone to cyclonic storms than the Bay of Bengal, do you think climate change off late has been changing the cyclone behaviour and challenging the fact that Arabian sea is less prone? Analyse.(250 words)
Why this question:
The article discusses how Cyclone patterns and occurrence over India’s western sea show a change and that the recent data suggests that the previously calm body of water has also started receiving tropical cyclones of high intensity in a small-time interval.
Analyze – When asked to analyze, you have to examine methodically the structure or nature of the topic by separating it into component parts and present them as a whole in a summary.
Key demand of the question:
The answer must analyse in detail why Arabian Sea is comparatively less prone to cyclonic storms than the Bay of Bengal and what has been the effect of climate change on it.
Structure of the answer:
Begin with brief introduction on the geographical aspects of Arabian sea and Bay of Bengal; their regular trends etc.
Discussion should include the following:
- First explain in detail why Arabian Sea is comparatively less prone to cyclonic storms than the Bay of Bengal – Almost 50 per cent of the storms do not sustain over its waters since the west-central and north Arabian Sea have a colder sea temperature than other adjacent regions. This cold sea surface temperature is not favourable for the development and sustenance of cyclonic storms.
- Then explain the recent unusualness around the Arabian sea; causative factors.
- Discuss the key role played by climate change in such a drastic change in the regular pattern.
Conclude by reasserting the importance of taking control over climate change to restore the natural course of the climate patterns and oceanic circulations.
