Do you know what causes wind? Well, broadly speaking it’s the sun... but more specifically, how the sun unevenly heats the Earth’s surface. That leads to areas of high and low pressure forming, and in ...

Isobars are lines/areas of equal pressure represented on a weather map. When isobars become very tightly grouped together it indicates a "tight pressure gradient" (steep slope). The tightly packed ...

MIKE MOSS SAYS: Phil, Winds would be perpendicular to the isobars is not for the rotation of the earth, which imposes a virtual force called the Coriolis effect. Over a significant time and distance ...

Using isobars on weather maps is completely accurate. Wind derives its initial speed and direction from changes in air pressure over distance, or pressure gradient force (PGF). This is why when ...

Our main concern in this article has to do with the relationship of a pressure system to its surroundings. Air pressure can be measured (atm, hectopascal, millibar) but the relative difference between ...

The basic answer to this question is related pressure. Wind is simply moving air caused by differences in air pressure in the atmosphere. The difference in pressure over some distance is called a ...

Wind is the movement of air caused by uneven heating of the atmosphere. Big differences in temperature over relatively short distances become more common as we nudge into the warmer months. The sun ...

NORFOLK, Va. — Over the last couple of weeks, you may have noticed the wind blowing more frequently as we transitioned from winter into spring. As a rule, spring is the windiest season for a lot of ...

Our much-ballyhooed storm system, now spinning across northern Alabam, may still kick up a few rumbles of thunder while you're trying to sleep in on Saturday, but it will be the winds that follow that ...

Strong winds are expected across Wisconsin this week. Gusts will range from 30-50 mph at times. A tight pressure gradient is the cause of strong winds. MILWAUKEE - A second Wind Advisory has been ...
