Formation of Tropical Storms
March 4th, 2009. Published under The Earth. No Comments.
Most tropical storms form over warm tropical oceans from preexisting regions of low pressure called tropical depressions. In these regions, air is moistened and warmed. The hot air rises, creating an area of low pressure. The rising air forms thunderstorms. Air moving in toward the low-pressure area travels across the warm ocean waters, and is moistened. This air provides more water vapor to fuel a storm.
As the hot, humid air rises, the water vapor in the air condenses to form clouds and rain. When water vapor condenses, it releases energy. This energy is called latent heat, or heat of condensation. It represents the amount of heat that is absorbed or released by a substance when the substance undergoes a change of phase—in this case, a change from water vapor to liquid water. A storm is a type of heat engine. Latent heat powers a storm and intensifies it. A storm will intensify as long as warm, humid air flows toward the center of low pressure that, in turn, continues to attract air. In addition, the change of wind speed and direction with altitude (called wind shear) must be small (change of wind speed of less than 27 km/h, or 17 mph) so that the heat from the thunderstorm remains within the storm’s center.
The rotation of Earth also affects the movement of air. In the northern hemisphere, Earth’s rotation deflects air from left to right, while in the southern hemisphere, it deflects air from right to left. This deflection is called the Coriolis effect . As air moves toward a low-pressure center, the deflection causes the air to spiral around the center rather than travel straight into the center. The inward spiraling of air causes the formation of circular bands of thunderstorms, which are a distinctive feature of tropical storms and hurricanes, along with spiraling winds. The spiraling winds rotate faster as they approach the center. Centrifugal force flings the rotating air outward, making it increasingly difficult for air to reach the center
As a storm intensifies and its winds gain strength, the winds reach a speed at which the air can no longer reach the center. The region corresponding to the maximum penetration of the spiraling air is called the eye wall. The eye wall contains the strongest winds. Inside this ring of strong winds, a calm area develops, known as an eye. A major distinction between a tropical storm and a hurricane is the presence of an eye in a hurricane. An eye forms when the winds near the center reach about 119 km/h (74 mph).
Within 5° of latitude north or south of the equator, tropical storms and hurricanes do not occur, despite frequent thunderstorms. The reason for this absence is the weakness of the Coriolis effect within 5° of the equator. In this equatorial region the winds can travel straight into the center of a low-pressure system and eliminate it. This process halts a cluster of thunderstorms before it can intensify into a tropical storm. Tropical storms and hurricanes also are very rare anywhere in the south Atlantic Ocean or in the eastern part of the south Pacific Ocean. This near absence is the result of relatively cold ocean temperatures and persistent large wind shear.
Tropical Storm
March 4th, 2009. Published under The Earth. No Comments.
Tropical Storm, weather system composed of a cluster of thunderstorms and of wind speeds near the surface of between 63 and 119 km/h (39 and 74 mph). Tropical storms develop out of storms called tropical depressions, in which wind speeds are less than 63 km/h (39 mph). If a tropical storm intensifies so that its wind speed reaches 119 km/h (74 mph), the storm becomes a hurricane. In contrast to a hurricane, a tropical storm typically does not have an eye, or calm area, at its center. Tropical storms form over large expanses of warm tropical ocean water. However, they do not form on the equator, and are very rare south of the equator in both the Atlantic Ocean and the eastern part of the south Pacific Ocean.
Tropical storms cause torrential rainfall and flooding, and can spawn tornadoes. Such storms can pose major threats to populated areas. For example, in 1994, tropical storms Alberto, Beryl, and Gordon caused nearly $1 billion worth of damage in the United States. The flooding caused by Alberto killed 30 people in Alabama and Georgia. In June 1972 tropical storm Agnes killed more than 100 people along the East Coast of the United States and caused catastrophic flooding in the northeastern part of the country. Tropical storms have been even more deadly and damaging in other parts of the world.
