Welcome back my fellow learners, today we are going to learn about how mother nature creates tornadoes and hurricane's.
A tornado is a fast spinning pocket of air which comes from thunderstorms, and begins from the ground. The makings of a tornado is mainly a thunderstorm, changing speeds in the wind and fast air rising. Should you watch a thunderstorm start, you will see the clouds start to build upward. This rising air causes the rain and hail to be formed out of the water within the air. Throw in rapidly changing wind speed, and the direction with the height creates the rapidly rising air to start to spin. The principle is the same with a toy spinning top. You use your fingers to spin it in opposing directions enabling the top to spin. This is similar to the wind which comes from different directions. Many thunderstorms do not create tornadoes due to the fact the spin cannot be balanced with the rising air from the surface. However, when the balance is right between rising air which comes into a thunderstorm, and the winds change height, then a tornado will be created. Tornadoes come in different categories, can can last a few seconds to several minutes.
A hurricane is a large thunderstorm which starts over the ocean. The mixture of warm ocean water, level winds, and low pressure will create one. The warm ocean will supply the moisture needed for a hurricane. The upper levels winds permit the developing hurricane to be cohesive, and the low pressure lets thunderstorms develop. As they develop, they are influenced over several hours and days by the rotation of the earth. This allows thunderstorms to begin developing into a circulation where they spin round a central point, this is referred to as the eye. Should the circulation stay over warm water, and upper level winds remain weak, then hurricane's winds will get stronger. The hurricane should begin to weaken once it hits land, over water which is too cold to maintain it, or should the upper level winds be strong enough to begin breaking the circulation.
