Hurricane Development

Hurricanes are a tropical cyclone, which means a rotation of closed low-level circulation of clouds and thunderstorms that originate from tropical and subtropical waters. Hurricanes are categorized by five categories, which determine the wind speed, the surge, and the pressure of a storm. These five categories help people be aware of how dangerous hurricanes can be: 1-minimal, 2-moderate, 3-extensice, 4-extrme, 5-catastrophic. Categories 1 and 2 have winds between 74-110 miles per hour, with a flow of 4-8 feet of water, and a sea level pressure of 980-979 millibars.

When we hear about hurricanes on the news or how one might be closing in on where we live we mostly think of how we are going to protect our self. However, there is one thing that I think most people do not stop and ponder, which is how does a hurricane even get forecast? From the direction it is going to be headed, to how it is categorized. The group that preforms all forecasting for tropical cyclone activity is the National Hurricane Center (NHC) and they cover the Atlantic and Eastern Pacific basins throughout North America. To start it begins with visual observations of the hurricane using reconnaissance airplanes, satellites, ships, buoys, radars, and an assortment of land-based equipment. Likewise, most of the storm’s projected path and

First, hurricanes form in warm water. Therefore, states or places closest to the equator will most likely get hurricanes. In different places, it has different names, like a typhoon or a cyclone. Hot air rises making less hot air below. It makes clouds, then circulate to form a hurricane. On the scale, a category 5 hurricane can have winds up to 157mph, maybe even more.

The hurricanes are usually considered intense storms of tropical regions characterized by strong winds exceeding seventy-four mile per hour, low-pressure center and thunderstorms. The center of hurricane the winds are usually light and the clouds are broken reason for that is air

This is an area over warm ocean waters where rain clouds are building. A tropical disturbance sometimes grows into a tropical depression. This area of rotating thunderstorms has winds of 62 km per hour (38 mph) or less. A tropical depression becomes a tropical storm if its winds reach 63 km per hour (39 mph). A tropical storm becomes a hurricane if its winds reach 119 km per hour (74 mph). Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the storms Atlantic Ocean or eastern Pacific

A hurricane is formed by warm and cool air mixing (Hurricane Katrina). The warm air rises which cause the cool air to fall (Hurricane Katrina). Once the warm air reaches the top, it cools, then

Most hurricanes that hit the United States begin either in the Caribbean or the Atlantic. Many of the worst start as seedlings coming off the coast of Africa. Like all tropical cyclones, a hurricane needs the warm water of the tropics, which feeds a storm with energy, in order to form. Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface. Another way to say the same thing is that the warm air rises,

Hurricanes are large, twirling storms that bring strong winds that can blow up to 74 mph or higher. There are two main ingredients that hurricanes need to form, warm water, and consistent winds. If a hurricane does form, it will include the eye, which is the clam center of the storm, around that there is the eye wall which is normally the strongest part of the storm, on the edges of the hurricane are the rainbands, which are swirling “arms” of clouds, rain, and thunderstorms, they can stretch out from the eye for hundreds of miles. After a hurricane forms it is tracked by meteorologists, and other scientists researching the storms, these people categorize it using the Saffir-Simpson Hurricane Scale, this scale is measured in five categories, category one has winds 74-95 mph, category two has winds 96-110 mph, category three has winds 111-129 mph, category four 130-156 mph, and finally category five has 157 mph winds and higher.

Leading up to a hurricane will start feeling warm and moist, allowing the air to become warm an humid, also allowing latent heat to spread. the next need is low pressure disturbance, also know as a tropical wave, to rise and make strong thunderstorms.if hurricanes try to form to close to the equator, it will not be strong enough to gather its self and rotate.

Hurricanes usually form over ocean areas near the Equator during summer months, since the ocean surface is at its warmest. The heat and moisture from the ocean provides the hurricane energy, and maintains it after its been formed. In this case, Hurricane Sandy travelled up north, growing colossal and relentlessly from the energy. However, if the supply of heat or moisture from the ocean is cut off, it will weaken the strength of the hurricane. Therefore, a hurricane is usually most destructive when it first moves over land. When a hurricane passes over land or cold ocean water, it loses its energy source of evaporating water and slowly dissipates.

Fierce winds flip autos, sink water crafts, and tear houses separated. Tropical storm winds extend from 74 miles 60 minutes (119 kilometers 60 minutes) to 150 ​miles a hour​ (241 kilometers 60 minutes) or more. Wind makes high waves and pushes the water onto shore. The water surge can be 30 feet (9 meters) high. That is as high as a 3-story building. Storm surges cause the greater part of the fatalities and harm.

According to the National Ocean Service, an organization that strives to protect coastal areas, a hurricane is defined as “a type of storm called a tropical cyclone, which forms over tropical waters” (1). That is to say, when a storm sustains winds with a count greater than 74 miles per hour, it is officially classified as being a hurricane. Generally originating over the Atlantic Ocean, hurricanes are formed when air from surrounding regions with high pressures rush to low pressure areas, causing the air above such warm, tropical waters to rise. As the warm, moist air rises and slowly cools off, water in the air begins to form clouds. Overtime, the number of clouds and strength of the winds significantly increases as a result of the heat and water evaporating from the ocean’s surface, creating a strong rotating storm that is soon recognized as being a tropical

Essentially, a hurricane is just a big storm. Hurricanes are formed when the moisture in the air evaporates and rises up until the heated moisture is twisted into the atmosphere. The cold and hot air will start “chasing” each other anti clockwise, and can reach speeds of 75 miles per hour.

The scientific name for this type of storm is a ‘tropical cyclone’; however, when formed over the Atlantic Ocean or the Eastern Pacific Ocean, they are called hurricanes. Hurricanes are formed in intense low pressure areas in these oceans. The fuel of a hurricane is water vapour from the surface of the ocean. This water vapour condenses to form clouds and rain which, in turn, warms the surrounding air. When there is little wind shear over the ocean (this is what usually takes the heat away), the heat will build up and cause pressure to form. This causes wind to spiral in on

A hurricane rotates in a clockwise or counter-clockwise direction due to a phenomenon that is known as the Coriolis effect. This video can tell you how it affects the spin of a hurricane. It's wind speeds that go over 64 knots or 118km/h. A hurricane can be 900km long and can last a week.This phenomenon is known as a cyclone in the Indian Ocean, but they are also named hurricanes in the Atlantic Ocean and typhoons in the Far East.
