Tornadoes could probably be considered as one of the most violent natural occurring disasters known to mankind. They are the funnel-shaped thunderstorms that spiral around the area where atmosphere pressure is low. Tornadoes are usually classified by using the Fujita Wind Damage Scale. According to the damage caused, there are actually seven types of tornadoes, but they can be classified into three main types: weak tornadoes, strong tornadoes and violent tornadoes. Most of the occurring tornadoes are Weak Tornadoes.They consist of Gale Tornadoes (F0) and Moderate Tornadoes (F1).
Hail and Tornadoes Description and Classification Tornadoes According to the Glossary of Meteorology, A tornado is "a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud." Tornadoes occur all over the world, but are especially prevalent in the United States. Tornadoes usually have wind speeds between 40 and 110 mph, forward speeds approximately 30 mph, and are usually around 250 feet across. They generally travel only a few miles before dissipating. The word "tornado" comes from the Spanish or Portuguese verb tornar, meaning "to turn."
A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are also called twisters or cyclones. Tornadoes come in many shapes and sizes, but they are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. While a hurricane which is also called a tropical cyclone is a storm system characterized by a low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. They strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor contained in the moist air.
People who are affected by a tornado can see the entire tornado come and go. Hurricanes are tracked by radar allowing for a great deal of time to prepare for its arrival. Tornadoes happen very suddenly and with little time for any preparation. Not only does the size of the storms differ, but also the appearance. Hurricanes are most often described as wet wind.
By only looking at a picture and forgetting that it can cause destruction you can see that they are something you obviously don’t see everyday and are a very interesting topic to discover and know more about. A tornado can be a very dangerous phenomenon of nature, but if you look at it from another angle they are incredible. Tornadoes are so full of power and strength; they vary in intensity regardless of shape, size, and location, though strong tornadoes are typically larger than weak tornadoes.

Effects of haboob to aviation are that it causes wind smear, damages a plane’s engines, and affects landing and taking off among others. This paper aims to explore some of the negative effects haboob causes to aviation. Introduction Haboob refers to a dust storm that is common in regions that experience extreme drought conditions (Miller, 2010). These regions mainly include arid and semi arid areas. When it occurs, there is transportation of large quantities of dust particles or sand particles affecting transportation through limiting visibility.
What is acid rain? Acid rain or acid deposition is a broad term that describes any acidic form of precipitation from the atmosphere. There are two types of acid deposition: wet and dry. Dry deposition includes acidic particles, gases and dust that are deposited from the atmosphere, whereas wet deposition includes rain, hail, snow and fog. Unlike dry deposition, winds can blow wet deposition hundreds of miles away from the source of emission, making it an issue for everyone.
A severe thunderstorm, by the definition provided by the Bureau of Meteorology can be hail with a diameter of 2 cm or more (about the size of $2 coin), wind gusts of 90 km/h or greater, flash floods, which is often the result of slow moving thunderstorms that causes a small area to receive most of the rain, tornadoes which are the rarest and most violent of the thunderstorm phenomena, or any combination of these. During a thunderstorm there will definitely be lightning and thunder but it is known that when struck, people do not glow or ‘fry to a crisp’ although the heart and breathing are often affected. Although most thunderstorms do not reach the level of intensity needed to produce these dangerous phenomena, all of them do produce lightning which can cause injury, damage, and even death. Thunderstorms occur throughout the world including the Polar Regions. Sever storms occur frequently in tropical rainforest area.
The climate is very bipolar though due to varying elevations and winds across the island. The east side of the island has the heaviest amount of rain which equals to about 3.5 meters a year. Not only does this side receive a great amount of rain it is also affected substantially more by the cyclones that wreak havoc on the tropical island. Rain clouds expel so much moisture to the east of the highest grounds the highlands in the central part of the island are much drier and cooler. The downside to the central highlands though are multiple thunderstorms that cause incredible damage due to lighting strikes.
The first disaster causes a lot of fires in the forests. Also, it throws a lot of volcanic gases which causes air pollution, such as, ash fall, CO2, and methane. "Mud volcanoes are one of the significant natural sources of atmospheric methane"(Dimitrov, 2002). The volcanoes affect the lands and cause landslides. On the other hand, the second disaster affects the cities more than the forests.
