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...

Random Weather Fact

What does Bombogenesis mean?


If you live along the east coast of the United States, you may have heard a meteorologist say that a storm system or low pressure area is bombing out or that bombogenisis is about to occur. What do these terms actually mean? When a low pressure system or mid-latitude cyclone moves off of the East Coast of the United States during the colder months of the year, there is a tendency for many of them to intensify rapidly due to the warmer waters of the Gulf Stream and the positioning of the low between two very different air masses. The air mass to the storm's north and west is usually very cold and dry while the air mass to the storm's south and east is very warm and moist. The stormís rapid intensification is known as ìbombogenesisî or I've heard meteorologists say that the storm is bombing out. The heat given off by the ocean is like fuel for the storm. Barometric pressure can drop rapidly causing the winds to increase rapidly. This is the reason noríeasters grow very strong and wreak havoc on the east coast. The warm moist air is extremely plentiful off the southeast coast. This energy feeds into the developing storm via the warm sector of the low. The warm air then rises as it encounters cooler air to the north. This rising motion causes condensation (clouds) to occur which then leads to precipitation. The condensation process actually creates heat (latent heat) and this process further adds fuel to the stormís energy. Upper level winds and conditions also add to the intensification process. If you look at a surface analysis map with the isobars, which are lines that connect equal barometric pressure, you will see that the lines are packed closely together in a storm that is bombing out. This indicates that the pressure gradient is steep and that the winds are strong. These storms sometimes produce hurricane force winds and they cover a large piece of real estate, extending farther than even the largest hurricanes.
