Discuss- This is an all-encompassing directive which mandates us to write in detail about the key demand of the question. We also have to discuss about the related and important aspects of the question in order to bring out a complete picture of the issue in hand.
Key demand of the question.
The question wants us to write in detail about the differences between a tropical cyclone and a non-tropical (mid-latitude cyclone).
Structure of the answer
Define a cyclone- e.g a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. Mention that there are two kinds of cyclones- tropical and mid-latitude (non-tropical).
- Discuss the features of a tropical cyclone. E.g A tropical (or warm core) cyclone (area of low pressure) usually forms over warm waters in the tropics. Air rises rapidly around the edges of the center of the storm. Hurricanes and tropical storms are (warm core) tropical cyclones etc.
- Discuss the features of a non-tropical cyclone. E.g A non-tropical (or cold core) storm has the coldest temperatures in the center of the storm. Temperatures cool as you move higher in the atmosphere and there is a trough at the highest levels. Unlike tropical (warm core) storms, winds are not as concentrated near the center of the storm etc.
Conclusion- mention that tropical cyclones can convert into non-tropical cyclones and both can have devastating effects on environment and livelihood etc.
