Near the surface, friction reduces the wind speed, which reduces the Coriolis force. Thus the pressure gradient force is balanced by friction and Coriolis force. In the northern hemisphere, surface winds blow counterclockwise and into a low, and flow out of a high in a clockwise direction.

Which factors or processes drive the movement of air in Hadley cells? -Cool, dry air falls towards the surface of the Earth, where increased air pressure causes adiabatic heating, resulting in warm, dry air.

The polar cell is a simple system with strong convection drivers. Though cool and dry relative to equatorial air, the air masses at the 60th parallel are still sufficiently warm and moist to undergo convection and drive a thermal loop.

The surface wind is the balance of forces on the wind that occurs at and near the Earth’s surface. The contrast to the geostrophic wind is that the surface wind introduces the force of friction. This results in an imbalance between the Coriolis and Pressure Gradient Force.

Without wind systems warm, moist air won’t move around. Water might still evaporate but it won’t travel meaning anywhere away from a large body of water will dry up. Plants, animals and humans will slowly die from dehydration with most water inaccessible as salt water or ice.

Wind has a very important role in aiding plants and other immobile organisms in dispersal of seeds, spores, pollen, etc. Although wind is not the primary form of seed dispersal in plants, it provides dispersal for a large percentage of the biomass of land plants.

Wind speed and direction are important for monitoring and predicting weather patterns and global climate. Wind speed and direction have numerous impacts on surface water. These parameters affect rates of evaporation, mixing of surface waters, and the development of seiches and storm surges.

Weak people are affected by the wind. It is because weak people break down easily and succumb to the adversities of life.
