Weather Dudes

Welcome to WEATHERDUDES.COM... We are currently focused on weather and climate of the Hampton Roads area of Virginia and the East Coast, as well as other significant national and global weather events that occur. The intent of this site is not to be just another weather website with five day forecasts featuring happy suns and sad clouds It is to provide various interesting and personalized features, which provide the visitor with a view of the weather from a different perspective.
Currently we have:
Dave's Weather Discussion Page, providing an insight to the local weather conditions and patterns, and the reasons behind the weather.
Tropical Weather, A collection of tropical storm and hurricane resources.
Recent Weather, Weather conditions for the past 10 days for the mid-Atlantic area.
Weather Glossary, Providing weather definitions from A to Z.
Links to Weather Sites, providing a growing collection of links to weather sites.
Weather Facts, A collection of interesting weather facts.
We will be adding more features on a regular basis. Feel free to look around, and let us know what you think. Check back often for new content...

What is a Sea Breeze?

Have you ever been on the beach and all of a sudden the wind shifts from off of the water and the temperature drops quite drastically? This sudden shift in wind which can be quite refreshing during spells of hot weather is most likely the result of a sea breeze. Sea breezes keep coastal areas cooler in the spring and summer on many, but not all days. What causes the sea breeze? It is really quite simple. Land heats up faster than the water. The air over the land begins to warm and since warm air is less dense than cool air, it rises as it is lighter than the cooler air above it. As the warm air rises over the land, the cooler air over the water begins to move in to replace the air that is rising over the land. This causes the wind at the surface to switch direction and blow from the water. As the afternoon wears on, the sea breeze normally strengthens and moves further and further inland. Its cooling relief can sometimes be felt many miles inland. Once the sun sets, the air over the land begins to cool and the air stops rising. The sea breeze stops blowing and many times reverses itself and becomes a land breeze as the night wears on. The land cools rapidly at night and the air begins to descend. If the normal gradient wind between the high and low pressure areas on the weather map is blowing from the land, it will resume at night. Even if there isnít much of a gradient wind, a light land breeze normally develops as the air moves out over the relatively warmer water. Some days, when the winds are blowing quite strong from off the land, a sea breeze will not develop. It takes certain conditions to produce a sea breeze. Note that sea breezes can enhance thunderstorm development as they produce a sea breeze front. This is where the cool, ocean air meets the opposing air flow as the sea breeze heads inland. This causes additional lift in the atmosphere, which can cause thunderstorm development. Sea breezes can raise humidity levels which can offset the cooling effect that they will bring to coastal communities. Most of the time, they are welcome relief to anyone living along the coast.
