How Do Mountains Affect Precipitation?

In basic terms, the two things needed for precipitation are moisture and lift. Temperature profiles and landmasses can also affect how much rain a region gets. Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of

The Sirocco Winds of the Mediterranean Sea

Over the central Mediterranean Sea, the strong south to southeast winds are known locally as Sirocco. These winds can significantly impact outdoor events, offshore operations, passenger ships, and local population centers. A Sirocco develops in response to low pressure moving east across the northern Mediterranean. The onset of this event typically occurs when a surface

The Power of Weather Symbols

What Causes Sea Fog?

Sea fog poses a significant challenge to marine operations in the northern Gulf of Mexico.

Houston’s History of Floods

Founded in 1836 where the Buffalo Bayou met White Oak Bayou, Houston has faced many floods. Not long after being established, the settlement flooded. Initially swamp land, people began to try and drain the area. Done with no planning, draining the land did not account for flooding rains. Flooding rains would come again and again

Outflow Boundaries and Gust Fronts

We have all experienced a gust front, or outflow boundary, before. It is a process associated with thunderstorms and can cause winds strong enough to cause damage. While tied to thunderstorms, the gust front gets to you before the storm does. Gust fronts and outflow boundaries are the same thing. Similar to a cold front,
