Differences in air pressure and the pressure gradient force are caused by the unequal heating of the Earth’s surface when incoming To show wind speeds, the pressure gradient is plotted onto weather maps using Within the atmosphere, there are different levels of air circulation.

One example of this type of wind would be katabatic winds. Polar Lows: Mesoscale Weather Systems in the Polar Regions, Cambridge University Press, Cambridge, pp 612. the surrounding points and so appears to move east. Gravity adds to the forces causing this general movement, because the higher pressure compresses the column of air near the center of the area into greater density – and so greater weight compared to lower pressure, lower density, and lower weight of the air outside the center. When you see a red capital letter "L" on a weather map, you're looking at a symbolic representation of a low-pressure area, also known as a "low." For example, a westerly is a wind coming from the west and blowing toward the east. A low-pressure area, low area or low is a region where the air pressure is lower than that of surrounding locations. The black arrows represent the basic flow of the wind:With areas of low pressure, cyclonic flow will closely parallel the isobar lines with a slight bend toward the center of the low. Moving air is called the wind and the movement of air is caused by two factors. So, strictly looking at this map and ignoring some other factors, there are new swells heading toward Bali/Indo, with arrival time 5 days from now, 7 days from now and 9 days from now.Hope that explains things a bit more and makes sense. the only difference from the case of the low pressure system is that air A low is an area where air pressure is lower than it is in the areas surrounding it. and Turner, J. However, because the planet is rotating, the air flow from center to periphery is not direct, but is twisted due to the The strongest high-pressure areas are associated with cold air masses which push away out of polar regions during the winter when there is less sun to warm neighboring regions. in geography and a Certificate of Advanced Study in Geographic information Systems (GIS). The explanation of wind flows around low pressure and high pressure systems The line from A to B would be rotating In a low pressure system, rising air cools and clouds begin to form. Air moves from high to low pressure along a gradient (similar to squash that is left in a glass of water becoming evenly distributed as it becomes less concentrated). The tendency for air to move from an area of high pressure to an area of low pressure is called the pressure gradient force (PGF). The tendency for air to move from an area of high pressure to an area of low pressure is called the pressure gradient force (PGF). The land-based Region where the atmospheric pressure at the surface of the planet is greater than its surrounding environmentWind circulation in the northern and southern hemispheresWind circulation in the northern and southern hemispheresOffice of the Federal Coordinator for Meteorology (2006).

Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator. So, have a look at the dark lines that converge at Bali and then extend out toward the West Indian Ocean. Wind is the movement of air across the Earth’s surface and is produced by differences in air pressure between one place to another. center are moving with a greater velocity than the one closer to the center.

Air pressure is created by the motion, size, and number of gas molecules present in the air.

From the viewpoint of points moving with the disk the parcel However, those in the middle and upper The 500 mb level is important for winds because by analyzing upper-level winds, meteorologists can learn more about weather conditions at the Earth’s surface. A parcel of air at point A would move toward the center of the low pressure In a high pressure system, air flows outward, and the deflection results in a clockwise rotation. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward.

These are the great circle paths that correct for a flat map vs. round earth. From the viewpoint of points on the disk the parcel would appear to

These winds are usually stronger than mountain-valley breezes and occur over larger areas such as a plateau or highland.

move toward the east. the case for the spinning disk shown below. east the line from A to B is rotating counterclockwise.

A simple rule is that for high-pressure areas, where generally air flows from the center outward, the High-pressure areas form due to downward motion through the On weather maps, these areas show converging winds (High-pressure systems are alternatively referred to as anticyclones. The rotation of the Earth viewed from above the South Pole is clockwise as is

When there is the formation of pressure gradient, air moves from the high-pressure region to the low-pressure region. clockwise.
