The boundary between two air masses is called a front. Fronts can be stationary, warm, occluded or cold and often affect the weather on Earth.Know More
Cold fronts cause warmer air to be pushed up, over the top of the colder air. The cold air remains close to the ground and eventually, the warmer air cools. Warm fronts also rise above cooler air. Because of the instability of the two air masses colliding, warm fronts often bring with them rain and thunderstorms.
Stationary fronts occur when a cold air mass and warm air mass meet, but both of them are too weak to overtake the other. Because two air masses of different temperatures meeting often cause rain and storms, a stationary front can cause heavy rain and flooding until one front gathers enough power to push the other out of the way.
An occluded front is more complicated than the others, because three air masses are involved. An occluded front happens when a warm front is caught between two cold fronts. The cooler fronts, because of their weight and density, move under the warm front and push it higher up.
Any of these fronts have the capability to cause dramatic weather changes such as temperature swings, high winds, rain, hail and severe weather.Learn more in Weather Forecasts
A front is a boundary between air masses that leads to a low pressure system as the atmosphere attempts to even out the temperature contrast. If there is enough moisture in the air, the uplift as these two air masses collide causes rain. If the temperature differential is large enough, the collision leads to thunderstorms, according to NOAA.Full Answer >
The two main factors that determine climate are temperature and the amount of precipitation an area gets. The climate of an area is determined over a long period of time, generally more than a lifetime.Full Answer >
The upper air winds are the fastest in the wintertime when the core wind speeds of the polar front can reach speeds of approximately 250 miles per hour. The polar jet stream travels around the earth at a height of about 5 to 8 miles above the surface.Full Answer >
Temperature affects air pressure by causing the air to either become more or less dense, which expands or lowers its pressure. Warm air is less dense than cold air, and as air becomes less dense, its pressure increases.Full Answer >
