Why is rain different in different places?
If you are wondering why some places get more rain than others, it has to do with the local climate. When they get too large for the updraft to hold, they fall down as rain. Therefore, places where air rises more frequently get more rain, and it rains more heavily when the updraft is stronger.
Which way does rain move?
The reason that they most often move from west to east is due to the jet stream. The jet stream is a narrow band of fast, flowing air currents located near the altitude of the tropopause that flow from west to east.
Does rain come from one direction?
Explanatory answer: “rain” moves in the direction that physical forces act on it, and that applies to rain bands, rain clouds or even single raindrops. Raindrops falls mostly down due to gravity and the exact direction is determined by wind.
How fast do weather fronts move?
However, depending on the length of the cold front, portions of the front may move toward the east, while other portions move south. Some sections of the front may move faster than others. Active cold fronts (slow moving) average 15 knots. Inactive cold fronts (fast moving) have an average speed of 25 knots.
What is the slowest moving weather front?
2. Warm Front. Warm fronts tend to move slower than cold fronts and are the leading edge of warm air moving northward.
What front moves slowest?
A warm front moves more slowly than the cold front which usually follows because cold air is denser and harder to remove from the Earth’s surface. This also forces temperature differences across warm fronts to be broader in scale.
What makes a front move?
A front is a boundary between two air masses of different densities. A front is a weather system that is the boundary separating two different types of air. Cold fronts move faster than warm fronts because cold air is denser, meaning there are more molecules of material in cold air than in warm air.
Do stationary fronts move?
Although the stationary front’s position may not move, there is air motion as warm air rises up and over the cold air, as a response to the ageostrophy induced by frontogenesis. A wide variety of weather may occur along a stationary front. Stationary fronts may dissipate after several days or devolve into shear lines.
What is a slow moving cold front?
With the slow-moving cold front, there is a general upward motion of warm air along the entire frontal surface and pronounced lifting along the lower portion of the front. The lower half shows the typical upper airflow behind the front, and the upper half shows the accompanying surface weather.
What are often linked to cold fronts?
A cold front commonly brings a narrow band of precipitation that follows along the leading edge of the cold front. These bands of precipitation are often very strong, and can bring severe thunderstorms, hailstorms, snow squalls, and/or tornadoes.
What kind of front can mean rain for days?
stationary front
What type of clouds are associated with warm fronts?
Warm fronts produce clouds when warm air replaces cold air by sliding above it. Many different cloud types can be created in this way: altocumulus, altostratus, cirrocumulus, cirrostratus, cirrus, cumulonimbus (and associated mammatus clouds), nimbostratus, stratus, and stratocumulus.
Why does a warm front usually bring a light and steady rain?
Warm air rides along the front (up and over the cold air mass), cooling as it rises, producing clouds and precipitation in advance of the surface warm front. Because the lifting is very gradual and steady, generally wide spread and light intensity precipitation develops ahead of a warm front.
What weather is caused by high pressure?
In general, low pressure leads to unsettled weather conditions and high pressure leads to settled weather conditions. In an anticyclone (high pressure) the winds tend to be light and blow in a clockwise direction (in the northern hemisphere).
Does high pressure mean good or bad weather?
High-pressure areas usually are areas of fair, settled weather. Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward toward these areas.
