Pressure gradient is the difference in pressure between ... Imagine you have a balloon filled with air. If you squeeze that balloon, the side with the most air has “high pressure” while ...

I once posed the question, "where does wind come from?" to a second grade class studying weather. The consensus answer: the ...

When the ground and vegetation are dry and the air has low relative humidity, high winds can also spread wildfires out of control. Even more intense winds can occur when the pressure gradient ...

Spring is a transitional season where temperatures generally rise, but cold air masses remain active. When a strong cold air mass moves southward, it collides with the warmer air masses, creating a ...

The same wave in the jet stream can lead to strong winds, blowing dust and fire danger in one region, while triggering a tornado outbreak and a blizzard in other regions. Windstorms can seem like ...

As summer weather and winter weather get closer together, storm systems get stronger and create tight air pressure gradients, making it windy. The other key factor is the melting winter snow pack ...

The opposite chain of events, with air converging at other locations, can form high pressure at the surface. In between these low-pressure and high-pressure systems is a strong change in pressure over ...
