Mid-day Sun can be seen overhead in Chennai twice a year, but not even once in Delhi .why?
Answers
The answer for your question is Chennai is closer to equator.
One can find the Sun aligns directly overhead to Chennai twice in a year but not a single time over Delhi. The reason behind this phenomenon is that the Chennai is located closer to the imaginary mid-line which we call equator. Apart from the above reason, the whole of South India falls under the Tropic of cancer which had moved the part to a tropical climate zone. There is a phenomenon that sun can be found directly overhead to the regions that falls under the 23.5°N and 23.5°S at least twice in a year. Chennai falls under the latitude of 13.5°N.
Chennai experiences the Midday sun twice a year while New Delhi .The idea that the Tropic of Cancer does not see the sun overhead twice a year has to do .The sun is never very far from being overhead at noon even in winter.
