describe a storm?

Question

the clouds, the rain

Answer 1

The tropical storm is a vast and nearly circular whirl of rapidly moving practically homogeneous air current with diameter 200 to 500 miles with a steep pressure gradient and very low pressure at the centre.These storms form between latitudes 10 degrees and 30 degrees in Northern and Southern hemispheres along the inter- tropical convergence zone and are known as hurricanes in America,typhoons inChina,Japan and Philipines,Willy-willies in Australia and cyclones in India.They do not develpo closer than 6 degree to 7 degree to the Equator as the deflective force(coriolis force) of the earth's motion is so slight in low latitudes that it does not favour the whirling motion which charcterises the storms.The clouds will be arranged in the different spiral bands which approach the centre.Around the eye of the storm,very high thunder clouds will be rotating in the anti clockwise motion in the Northern hemisphere.Torrential rains will be experienced close to the eye wall.

Answer 2

any disturbed state of a planets atmosphere,especially affecting strong wind(wind storm),thunder and lightning,and the clouds full of rain

Answer 3

Describe what type of storm you are asking about. There are many different types.

Answer 4

ok here goes:

ACID RAIN
Acid rain attacks wildlife, crops and lakes. It can cause the death of forests and damage buildings and monuments. It is even harmful for human beings. Acid rain is caused by pollution. Pollutants like sulphur dioxide and nitrogen oxide stay in the atmosphere and eventually react with the moisture in the air. When this polluted moisture falls to the ground, it is called acid rain.

HURRICANS
develop from belts of low pressure called easterly waves. These regions of low pressure occur in ocean winds called trade winds. On certain occasions, the easterly waves form into tropical depressions. The next stage in development is a tropical storm, with winds of up to seventy three miles per hour. Any wind speed higher than that and it is a hurricane. The fuel that powers hurricanes is derived from latent heat from the condensing of water vapor. Thunderstorms can produce up to ten inches of rain per day, and thus produce an incredible amount of energy, up to 24 x 10¹¹ kilowatt hours per day on average. This is the equivalent of how much power most industrialized nations use in one year (such as the United States). Winds swirl around the eye. The eye has a diameter of about twenty miles across and has very few winds or clouds. Surrounding the eye are storm clouds called wall clouds. It is within these clouds that the heaviest rains and strongest winds occur. These wind speeds are kept up by the differences in horizontal pressure between the eye and outer regions of the storm. Initially, when a hurricane forms, its forward movement is very slow (fifteen miles per hour), but as it gets farther away from the equator, its speed increases up to sixty miles per hour in middle latitudes. But in addition to gaining speed as is moves away from the equator, it also begins to die. Eventually it looses its source of power as it passes over land and gets ripped apart by friction. Hurricanes usually only last between five and ten days.

THUNDERSTORMS
A thunderstorm, also called an electrical storm, is a form of weather characterized by the presence of lightning and its attendant thunder produced from a cumulonimbus cloud.[1] Thunderstorms are usually accompanied by heavy rainfall and they can also be accompanied by strong winds, hail and tornadoes. In the winter months, snowfall can occasionally take place in a thunderstorm. Such is often termed thundersnow. Thunderstorms form when significant condensation—resulting in the production of a wide range of water droplets and ice crystals—occurs in an atmosphere that is unstable and supports deep, rapid upward motion. This often occurs in the presence of three conditions: sufficient moisture accumulated in the lower atmosphere, reflected by high temperatures; a significant fall in air temperature with increasing height, known as a steep adiabatic lapse rate; and a force such as mechanical convergence along a cold front to focus the lift.

WIND


A big layer of air called the atmosphere surrounds the Earth. The air within this layer moves from place to place when it warms up or cools down. This moving air is known as wind. Winds move moisture and heat around the world and also produce much of our weather.

As we know, the strength of the wind can vary enormously. Sometimes air moves slowly and the wind is barely noticeable. When the weather is clear we may experience a gentle breeze, when the wind is still very light but we can feel it on our faces and in our hair, and we may hear leaves rustling. At other times, the air can move very quickly and become a gale or hurricane, blowing down trees and damaging cars and buildings. As equatorial areas are heated most, the air above them warms and rises as it becomes lighter than the surrounding air, causing an area of low pressure. In cooler areas, the air sinks because it is heavier and results in an area of high pressure. Winds will blow as air is squashed out by the sinking cold air and drawn in under the rising warm air. Any difference in temperature like this will always cause a difference in air pressure – and therefore winds will blow.

LIGHTENING
Before lightning is formed, the cumulonimbus cloud of thunderstorms must become electrically charged. In most rain clouds, the bottom of the cloud is negatively charged and the top is positively charged. It is not known how the cloud becomes charged, but scientists have formed numerous theories to try to explain this phenomenon. These theories have been divided into two main categories: those that require ice and those that do not. However, meteorologists are leaning toward the theory that requires ice because lightning is not often seen unless ice has formed in the upper layers of the rain cloud.

Theories

The first theory describes how ice gains a negative charge while frozen and unfrozen water keeps its positive charge. Another theory shows how when large droplets fall swiftly, they gain a negative charge, while slowly falling water gains a positive charge. Theories that do not require ice gives the explanation that the cloud gets its charge by attracting negative charges from the ionosphere. These negative charges are pushed to the base of the cloud by strong downdrafts, while the positive particles are pushed upwards by warm air within the rain cloud.

Strokes

Eventually the negative charge of the base of the cloud gives the earth a positive charge. When the electrical potential reaches approximately ten thousand volts per centimeter, ionization occurs along a narrow path and the result is a flash of lightning. The negative particles descend from the base of the cloud to the ground. However, most lightning flashes are not a single event, but rather numerous strokes followed by a leader stroke. There can be up to 42 strokes to a lightning bolt. The time between successive strokes is 0.02 seconds. The average bolt lasts only one fourth of a second.

THUNDER
The giant spark of electricity makes the air so hot so quickly, that the air bumps into the cooler air around it. And it bumps so hard that it makes a cracking sound.
