Consider the following statements:

1.Tropical cyclones do not form at the equator because the low pressure gets filled instead of getting intensified.

2.The winds in the upper troposphere are free from frictional effect and Coriolis force and are known as Geostrophic wind.

3.The higher the pressure gradient force, the more is the velocity of the wind, and the larger is the deflection in the direction of the wind.

Which of the statements given above is/are incorrect?
