HURRICANES and WINTER STORMSFOR YOUR NOTES:
A hurricane is a tropical storm that has winds of 119 kilometers per hour or higher. Hurricanes also form in the Atlantic, Pacific, and Indian Oceans.
**In the western Pacific Ocean, hurricanes are called TYPHOONS.

HOW HURRICANES FORMNOTES:
A typical hurricane begins over warm water as a low pressure area. A hurricane gets its energy from the warm, humid air at the ocean's surface.
The center of a hurricane is a ring of clouds surrounding a quiet "eye."

Hurricanes last longer than other storms, usually a week or more. After the hurricane slows down, heavy rainfall continues for many days.

Winter StormsA winter storm can form when humid air cools below 0 degress Celsius.
Two of the snowiest cities in the United States are Buffalo and Rochester in upstate New York. Areas near the Great Lakes are affected by something called LAKE-EFFECT SNOW.

WRITE THIS DOWN:
LAKE-EFFECT SNOW happens when cold dry air moves across the warmer water (Great Lakes) and picks up water vapor. When the air reaches land and cools, lake-effect snow falls.
