The following six (6) items consist of two statements, Statement I and Statement II. Examine these two statements carefully and select the answer using the code given below. Statement I: Geostrophic wind blows above a height of 600 metres, parallel to the isobars. Statement II: Geostrophic wind is the horizontal wind velocity, in which the Coriolis force balances the horizontal pressure force.?

Option 1 : Both the statements are individually true and Statement II is the correct explanation of Statement I

Isobars are those lines on the weather map joining places with equal atmospheric pressure.

• A wind blowing at a height of 600 m from the Earth Surface is called Geostrophic wind.
• These geostrophic winds blow parallel to the isobars.
• It is because when isobars are parallel and straight, the pressure gradient gets balanced by the Coriolis force and thus geostrophic winds start blowing parallel to the isobars.
• The Geostrophic wind blows in the horizontal direction and in the same direction as the isobars.
• Hence, both the statement is correct and Statement II is the correct explanation for Statement I.
