Senator Hillary Rodham Clinton, Former First Lady of the United States, was given the Humanitarian Award in 1994 for her advocacy on behalf of children and children's issues. Laura Bush, First Lady of the United States, received the 2002 Humanitarian Award for her lifelong commitment to education.
The pressure gradient force (Pgf) is a force that tries to equalize pressure differences. This is the force that causes high pressure to push air toward low pressure. Thus air would flow from high to low pressure if the pressure gradient force was the only force acting on it. How the coriolis force works on a rotating disk. However, because of the earth's rotation, there is second force, the Coriolis force that affects the direction of wind flow.
The forces that govern wind velocity include the pressure gradient force, the Coriolis âforceâ (an apparent force due to Earthâs rotation) and friction. The pressure gradient force is what causes the wind to blow. In the atmosphere, pressure differences are a result of changes in density due to warm and cold air. When warm and cold air is close together, we have a pressure gradient.
