Impact on Nature : Benefits
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.

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.

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

/a/hurricanecauses.htm
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

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.

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.)
