Essay On Cyclone For Class 5 Students In Easy Words – Read Here

Introduction:

The planet Earth has suffered during its history of different cyclones, which are winds that blow in opposite directions. We must take care of our world and do what is in our hands to protect not polluting, collaborating with recycling items since natural disasters are not in our hands to prevent it.

How Is A Cyclone Formed

In the northern hemisphere, a cyclone is low-pressure systems with rainy and electrical activity, whose winds rotate counter-clockwise against the clock.

Tropical Depression

The maximum average wind at sea level reaches a speed in 1 min 62Km / h or lower.

Tropical Storm

Well-organized cyclone of the molten core in which the wind reaches level e in 1 min from 63 to 117 km / h.

Cyclone

The average maximum wind that reaches is 118Km / h or higher in 1 min.

As the sea temperatures have to be more than 80 F, the hurricanes will form in different places in different months of the year, usually at the hottest time.

Cyclone occurs in all tropical ocean areas except the South Atlantic and the South Pacific. Remember that the hurricane needs a lot of ocean to gather strength and to nourish itself, and it moves with the rotation of the earth towards the west.

Structure Of A Hurricane

This steam engine has a center that is warmer than the air that surrounds it. It receives its energy from the condensation of water vapor. The vapor (originated by the evaporation of the sea) begins to expand and to ascend quickly.

When reaching the high areas of the atmosphere, where the temperature is no longer so high, this vapor condenses again, releasing a large amount of energy and causing huge clouds (which can reach 15,000 m in height) and abundant rain.

Satellite

These phenomena are distinguishable in the satellite images shown in the TV weather forecast. In the lower area of ​​the hurricanes (up to 3,000 m), the air is sucked towards the center of it. In the middle levels, there is cyclonic circulation of ascending air (it revolves around the center). And in the upper part of the hurricane.

First Alarm Signals

Attention should be paid to possible undulations in the isobars. Sometimes they can form very closed loops and be the source of a very active low-pressure system. Remember that a small but intense tropical cyclone can approach without alarming.

Nowadays satellite images are the basis of cyclone forecasting throughout the world and as its interpretation is perfected, more accurate are the predictions.

Rotational Signal

During the cyclone season, meteorologists receive satellite pictures every hour. They look for large clusters of storm clouds over tropical oceans, which could be embryonic cyclones. When they identify them.

If the cyclone moves less than 240 km from the coast, it is within reach of the radar and can be followed with precision. However, even in this case, there is a degree of uncertainty, since cyclones act unpredictably.

The cyclone is the greatest inherent danger to human life when it reaches the coast. The loss of lives can be reduced by evacuating the area, but material destruction is inevitable.
