Pressure gradient means rate of change of pressure between two points, as the wind always flow between high pressure to low pressure zone. Steeper will be the gradient, wind flows more strongly between high pressure to low pressure zone due to pressure gradient force. When the wind flows between high pressure to low pressure zone, due to Coriolis force the wind deflects from its direction, wind coming from the northern hemispehere deflects towards its right and wind coming from the southern hemisphere deflects tworards its left and after thr deflection when the coriolis force equals to pressure gradient forcez the wind starts to blow parallaly to the isobars.

A-B. In a surface high pressure system, gradient winds are ____________ than geostrophic winds, and blow clockwise while turning ______________________ across isobars due to friction. C. In a _____________________, the land heats more quickly than the water surface during the daytime, causing a breeze that blows onshore from a small body of water over the land. D. In the ____________________, the continent cools faster than the ocean, resulting in a dry surface circulation that blows offshore. E. A vast amount...
