How Are Winds Formed? | Sciencing
Wind pressure is the force of the wind nlowing against something. Air pressure is the wieght of the atmosphere. Imagine a column of air 1 inch. The wind blows because of differences in air pressure from one location to another. Wind blows from areas of high pressure toward areas of low pressure. in terms of temperature, relative humidity, air pressure, and wind speed. Akhtari  also found a strong relationship between weather (hours of .. designing recommendation systems , and of course, marketing .
A more significant force affecting wind patterns, though, is the Coriolis force. The wind is no exception and is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The magnitude of the deflection is the least by the equator and the greatest around the poles.
Weather Variables: Air Pressure, Temperature & Density
Other forces affect the behavior of winds as well. A commonly known one, friction, is a strong influence over winds near the ground. Friction always acts in opposition to the wind velocity and the flow of air in general. This also reduces the effects of the Coriolis force, and the atmosphere adjusts to that by turning the wind toward low pressure.
The Coriolis force and friction combined, and balanced with the horizontal pressure gradient force, cause a balance in the atmosphere that explains the spiraling motion, instead of a straight inward or outward motion, around low- and high-pressure systems.
Sciencing Video Vault With winds directed toward low pressure and the fact that air rises in a low-pressure area, stormy weather results as water reaches its condensation point in the atmosphere.
Clouds and precipitation are the result. Also, with temperature changes directly affecting pressure, a large change in temperature can also generate wind.
Like a set of siblings, each variable is closely related to the others whether they like it or not! Pressure, Temperature and Density Let's look at air pressure first. Though you can't see them, air is a cocktail of molecules that fly around and bump into each other.
Think of the molecules as billiard balls - as they bump into each other, they push each other around. You aren't going to notice one molecule bumping into another one, but if you add up all these tiny collisions and pushes, you might start to feel it! Those molecules also have weight, and between the weight of the air pushing down and the collisions between molecules, we get air pressure.
So, how does air pressure relate to temperature? Well, remember how I said the air molecules are moving around and bumping into each other?
Wind & Air Pressure
If they move faster, they bump into each other harder and more often. This happens when the temperature of air is increased.
Warm air molecules have more energy, so they move faster and create more pressure. Likewise, cold air has less energy and therefore exerts less pressure on its surroundings. Density also plays a role. The denser the air is, the more molecules there are in that given space. It's like the difference between having a large party packed into a tiny living room versus having that same large group of people in a big recreation hall.

The denser the air, the more collisions there are between molecules because there is less room for them to avoid running into each other, so we get more air pressure. So, you can see that density, temperature and pressure work together to change the conditions of the air. When heat is added, air temperature and pressure both increase.
And, when the density of air changes, the pressure and sometimes the temperature does as well. Adiabatic Processes Now that you know how the three variables work together, let's take a look at how they affect weather.
