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.
According to Merriam-Webster’s dictionary, the definition of snow is, “precipitation in the form of small white ice crystals formed directly from the water vapor of the air at a temperature below 32 degrees Fahrenheit.” Whereas, rain is defined as, “water falling in the drops condensed from vapor in the earth’s atmosphere.” There are many similarities and differences to rain and snow because of formation, destruction, weather apparel, and kids enjoyment. Another similarity between snow and rain is that they can both be very destructive. Large amounts of rainfall can produce floods. Floods can destroy homes, ruin farmer’s crops, and even loss of human life. Treacherous rainfalls are also able to produce landsides.
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."
Some natural causes for these chemical reactions include erupting volcanoes and rotting vegetation. Eruption of volcanoes can release certain chemicals that react with the rain, and it’s the same case with rotting vegetation. These reactions usually release nitrogen oxides and sulfur oxide. This can be deposited in two ways, dry and wet deposition. Wet deposition is acid rain falling directly into the ground where the area is usually wet in rain, snow, or hail.
Description of a haboob Haboob comes from an Arabic word “habbe”, which means wind. “Haboob is a type of an intense dust storm usually carried on an atmospheric gravity current” (Weather Online, 2011). This type of dust storm is common in arid areas. They have occurred in Sahara desert and Arabian Peninsula. In America, haboobs are common in the deserts of Yuma, Arizona and Phoenix.
This is the result of factors such as solar heating or when air is forced uphill. As the humid air rises, it cools and condenses to form a cloud. As more humid air rises the cloud grows in size, extending higher and the water droplets therefore grew larger. The higher the cloud rises, the more chance there is that ice crystals may form because of the low
Normal conditions, before El Nino events occur, strong trade winds move surface waters westward. As this occurs the water becomes warmer. When water becomes warmer it causes the air to rise and cool causing torrential rainfall. When El Nino occurs there a warm upper ocean layer, which is poor in nutrients and a cold lower ocean layer, which is rich in nutrients. The cold water is brought when the surface current flows westward in a process known as upwelling.
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).
Second, the process of the two natural events is different than each others. The volcano usually happens and forms near the plates boundaries of the ground. First, the crust is moving a little bit and causing melt because of decreasing the
But that is not true due to the fact that if ghosts would cause a temperature difference they would have to cause a temperature increase due to the fact that they increase the energy in the atmosphere causing the kinetic energy in the atmosphere to increase and temperature is the average amount of kinetic energy in an area. “Cold spots are small self-contained air pockets that feel colder than the ambient temperature; they have been recorded between 10-40 degrees lower than the ambient air. They are usually found in the location at the approximate time of a manifestation. Witnesses frequently describe cold spots, or relate that they felt a chill upon entering the area {of a manifestation}. It is theorized that these cold spots are the result of the manifestation using the heat energy of the surrounding air as fuel” (Ghosts of Earth).
