Essay on Typhoon
A typhoon is a tropical storm associated with an area of extremely low temperature. It builds up over warm seas and feeds on the energy and moisture from water that evaporates from the surface. Once a wind in a depression gathers speed and reaches 120 kilometer per hour (75 miles per hour) it develops in the northwestern part of the Pacific Ocean between 180° and 100°E. It is a sophisticated Tropical Cyclone. It is characterized by a deep strain center, violent rain bands and vigorous winds. It commences over tropical or subtropical waters and whirls clockwise in the southern hemisphere and counter-clockwise in the northern hemisphere. The tropical cyclones moving into the western Pacific re-designated as typhoons.
When a typhoon moves from sea to land, it brings rain and wind that can cause great extermination and loss of life in just a few minutes. The massive rain and tenacious winds come from near the typhoon’s center, on the edge of its eye. The eye of a typhoon develops as the swirling clouds moves faster. The eye is calm because centrifugal face pulling wind into the center is balanced by air pressure pushing wind out. Typhoon spins in an anticlockwise direction in the Northern Hemisphere.
Identical phenomena of Typhoon in the eastern north Pacific are called hurricanes. Hurricanes are giant, twisted tropical storms that can load wind speeds of over 160 miles (257 kilometers) an hour and release more than 2.4 trillion gallons (9 trillion liters) of rain a day.
Hurricanes begin as tropical upheaval in warm ocean waters with surface temperatures of at least 80 degrees (26.5 degrees Celsius). These low pressure systems are sustained by energy from the warm seas. Hurricane is the occurrence for a cyclonic storm system that forms over the oceans. It is created by evaporated water that comes off the ocean and becomes a storm.
Typhoons and Hurricanes are the same kinds of tropical storm. The tropical storm which came in Western Pacific or Indian Oceans is known as “Typhoon” although the tropical storm which came in Atlantic Ocean is “Hurricane”.
Short Essay on Tornadoes
Tornadoes are fierce whirlwinds that occur most often in the United States. When cold air meets warm, moist air, the warm air rushes upwards and form cumulonimbus clouds. As the warm air flows upwards, downward air current forms. This creates a thunderstorm. If a strong wind blows through the clouds, it can twist the rising air currents into a whirlwind. This whirlwind may spin faster and faster until it forms a tornado.
The winds of tornadoes usually spin at about 500 kilometer (300 miles) per hour. Tornadoes zip along at speeds of up to 100 kilometer (60 miles) per hour. Although, they generally last less than an hour, tornadoes can cause a lot of damage.
In 1925, one of the fastest and largest tornadoes killed 689 people as it traveled 354 kilometer (220 miles) across Missouri, Illinois and Indiana.
