Thunderstorms advantages and disadvantages
You should know that the thunderstorms are small , intense weather systems that make strong winds , heavy rain , lightning , and thunder , They serve to cool the earth , They create rainfall and remove the pollution from the air , They are a direct result of the atmospheric heating and the increased air convection .
It is very important to know that the thunderstorms provide the water to the vegetation and also to the lakes and the reservoirs , They can happen anywhere with two conditions which are the air near the Earth’s surface must be warm and moist ( with lots of liquid ) , and the atmosphere must be unstable .
You have to know that the storm winds distribute the seeds and the pollen , and they help remove the old and weak vegetation and so they make way for new growth , The lightning strikes liberate nitrates that fertilize the soil , The lightning produces about 20 percent of the nitrogen to the soil per year .
You should know that the updrafts and other wind effects remove large amounts of pollution , transporting it aloft , The storm rainfall washes the pollution out of the air , The thunderstorms are very active electrically , And the Lightning is an electrical discharge which happens between two opposite charged surfaces .
It is very important to know that when the lightning strikes , The energy is let out which moves to the air and makes the air spread quickly and send out the sound waves , The thunder is the sound that comes from the rapid spread of air along the lightning strike , The thunder is slower than the lightning because the light is faster than the sound .
You have to know that although the thunderstorms are dangerous , They are also a great blessing , They can be a great help to man and all living creatures , We get lots of water for many continents during the summer , The rain from the thunderstorms washes away many of these pollutants out of the air .
You have to know that without the thunderstorms , many continents would become dry , The fish would die , The crops would fail , and the animals would die , They helps our earth maintain its electrical balance because the lightning helps transfer the negative charges back to the earth .
It is very important to know that the lightning helps fertilize the soil , The heat and the pressure from the lightning turns nitrogen and other gases in the air into useful compounds that are a natural fertilizer which help the plants make vital proteins , And it produces the ozone that is a vital gas in our atmosphere .
You should know that the thunderstorms are dangerous , only about 10% of thunderstorms are thought severe , The severe thunderstorms cause high winds of more than 56 miles per hour ( 90 km/h ) , The hail , the flash floods , the tornadoes , And the hailstorms damage the crops , They damage the metal on cars , and they break the windows .
It is very important to know that the sudden flash floods that happen because of heavy rains is the biggest reason for weather-related deaths , The lightning that happens with all the thunderstorms makes thousands of forest fires each year , The lightning kills many people , and it injures hundreds of people a year .
You should know that the streams and the rivers cannot carry all the water , so they flood , The most severe flash flood makes the water level rise dangerously in the streams , the dry places , or the canyons , The flash floods can make terrible mud slides and they can move very quickly , They can roll big rocks , They tear out the trees , and they destroy the buildings and the bridges .
How can you keep safe in the storm ?
You should stay away from the water because the water conducts electricity , You should not stand on the hilltop , Try not to be the tallest object , If the lightning comes near , try to find shelter in the house , the car , or in the low place under some small trees but not in a shed , Inside a house .
You should not use the telephone or any electrical things , You should not take a bath or a shower , You should not look for shelter under a tree by itself , You have to stay away from metal ( like the pipes , the fences, and the wire clotheslines ) , If your hair stands on end while outside , You have to drop to the ground and curl up in a ball-like shape .
You should stay out of low places if there is a flash flood , The cars should not be driven through the water that is flowing over a road or bridge , The flowing water can push a car right off the road or the bridge , It takes two feet of water to float most cars .
You should know that the road under the water might have been washed out , leaving a deep hole , The flash flood can easily turn over a car and trap everyone inside , So , if your car stops in the flood waters , You have to get out as fast as possible and run to higher ground .
