Hurricanes provide ecological benefits to tropical and sub-tropical environments. Rainfall gives a boost to wetlands and flushes out lagoons, removing waste and weeds. Hurricane winds and waves move sediment from bays into marsh areas, revitalizing nutrient supplies. Impact on Nature : Benefits Ecological, tropical, sub-tropical, wetlands, lagoons

A hurricane is a huge storm! It can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph. http://www.weatherwizkids.com/weather- hurricane.htm

Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Hurricanes rotate in a counter- clockwise direction around an "eye" in the Northern Hemisphere and clockwise direction in the Southern Hemisphere.

What causes Hurricanes In recent years, the relationship between hurricanes and climate change has become a source of public interest, significant scientific debate, and a focus for current research http://www.hurricanescience.org/science /science/climate/ Human activities such as deforestation and greenhouse gas emissions from a wide range of industrial and agricultural processes are contributing to those temperature changes at a greater rate today than in the past environment.nasa.gov/od/globalwarming /a/hurricanecauses.htm

Weather Maps 1) WEATHER MAPS indicate atmospheric conditions above a large portion of the Earth's surface. Meteorologists use weather maps to forecast the weather. http://www.weather.gov/ http://www.spc.noaa.gov/products/wwa /

When does hurricane season start? The Atlantic hurricane season is from June 1 to November 30, but most hurricanes occur during the fall months. The Eastern Pacific hurricane season is from May 15 to November 30. (Below is a graphic that shows you when hurricanes are most active across parts of the world.)
