Which direction does Pennsylvania weather generally move in?
the west
Climate of Pennsylvania. Pennsylvania generally has a humid continental climate characterized by wide fluctuations in seasonal temperatures, with prevailing winds from the west.
Where does the prevailing wind come from?
Winds occur where high-pressure air masses seek low-pressure areas. Prevailing winds are largely predictable and named for broad areas of the Earth over which they form. Convection cells circulate air flow and help regulate temperature around the globe.
What is the windiest month in PA?

What part of Pennsylvania gets the least snow?
One of the least snowiest portions of Pennsylvania is the Susquehanna Valley eastward towards the Philadelphia region. We are in a unique spot being just east of the Appalachians. As cold air from the west moves east across the state, the air sinks down the east side of the mountains.
Why does the wind drop at night?
At night, surface cooling reduces the eddy motion of the air. Surface winds will back and decrease. Conversely, during the day, surface heating increases the eddy motion of the air. Surface winds will veer and increase as stronger winds aloft mix to the surface.
Why is there less wind at night?
The wind speed tends to decrease after sunset because at night the surface of the Earth cools much more rapidly than does the air above the surface. As a result of this difference in cooling ability, it doesn’t take long for the ground to become colder than the air above it.
What are the 3 types of prevailing winds?
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10).
