Q Upsc 2020
1. The jet stream occur in the Northern hemisphere only
2. Only some cyclone develop an eye
3. The temp inside the eye of a cyclone is nearly 10c lesser than that of the surrounding.
a)1only
b)2&3 only
c) 2only
d)1 and 3only
I just knew the first statement was wrong and 2nd was correct automatically after elimination.
but from where did the third statement come form
I ended up marking b but correct answer is c
any book ? any logic ?
I just have read the NCERT
If the temperature inside the eye region is lower (by any degree, let alone 10), the pressure will have to be higher (than the rest of the cyclone).
We know that the eye is the region of lowest pressure. So the eye must have the highest temperature of all parts of cyclone
