As storm relative velocity helps analyze the motion of the winds within the storm, information like the rotation of the storm and the speed of the winds can help investigate the chances of the storm developing into a tornado. If the storm appears to be a threat, nearby communities can be notified to take precautions and leave if necessary. Although base velocity can be used for the same reason, the speed of the storm can affect the results of the speed and rotation of winds. Therefore, storm relative velocity is more accurate and reliable than base velocity in determining the threat of a
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.

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
There are several stages in a hurricane. The first stage of a hurricane is a category one. To be a category one hurricane the hurricane must have a maximum sustained speed of at least 74-90 mph.(119-153 km) To be a category two hurricane the wind speeds will he about 96-110 mph(154-177 km). A category three hurricane and higher is considered a major hurricane. A category three hurricane has winds of 111-129(178-208 km) mph. A category four hurricane has winds up to 130-156 mph (209-156 km).A category five hurricane has winds up to 157 mph () or higher because they have not classified a category six to limit the category 5 hurricane mph. The word hurricane also means typhoon. Typhoons are called typhoons because they are mostly in coastal
Hurricanes are, highly dangerous and large swirling storms that begin over water and they sometimes end up on land. On October, 4th 2016 Hurricane Matthew hit the coasts of Haiti with 130 to 150 mph wind speeds which means it was a Category 4 hurricane. Hurricanes such as Matthew are tracked by forecasters whose job is to give people watching or listening an idea of strong the winds are. The forecasters use a scale called the Saffir-Simpson Hurricane scale it is used to track the winds and categorize the hurricane. The scale has 5 Categories beginning at 74 miles per hour and ending 157 mph and it can go even higher. Lastly, a hurricane has three parts, first the rainbands, the rain bands have rain, thunderstorms and sometimes tornadoes, next
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.
A hurricane is a tropical cyclone with maximum wind speeds of at least 74mph and is accompanied by thunderstorms. For the hurricane to take place the ocean surface has to be 80 degrees, a sufficient amount of water vapor and a sufficient distance from the equator. This creates what we call, the Croiolis Effect.
I decided to prepare this sheet as a short description of some of the important themes that we’ve taken up in lecture in the second half of the quarter. In preparation for our final, I would recommend reviewing your notes and textbook, putting together answers to each of these. Indeed, if you have good answers in your head (making use of examples shown in class) for each question, you should do well.
The wind speeds of a tornado and a hurricane are uncommonly different. Such as, the wind speeds of a tornado can be anywhere between 40mph to +318mph! On the contrary, the wind speeds of a hurricane can be anywhere between 74mph to +155mph! The hurricane`s scale is category one through category five. Category one is 74mph to 95mph, category two is 96mph to 110mph, category three is 111mph to 130mph, category four is 131mph to 155mph, and category five is >155mph. Wow! that’s fast!
They track tropical storms and hurricanes and they warn citizens of danger. The NHC can measure where and how major the hurricane is gonna be. They are associated with the National oceanic and atmospheric administration. Scientist use satellites or planes to monitor the storm. Hurricanes are measured using the Saffir- Simpson Hurricane. There are 5 types of categories. The highest is a category 5 hurricane with 155 plus wind speeds and a surge storm of 18 plus feet. Even if a category 5 hurricane has stronger winds a category 3 hurricane can cause more
Red has the longest wavelength on the visible light spectrum, so invisible light just beyond red would have a longer wavelength. Observations The temperature of the area just beyond the red light was consistently the highest (if sometimes tied with the temperature in the yellow or blue light) of the four temperatures. The temperature in the yellow light was the second highest, then blue, then the one in the shade.
In this study, I have examined multiple hazards from land falling Hurricane Isabel and the effects it had on Maryland. Hurricanes are areas of low air pressure that form over oceans in tropical climate regions. Hurricanes are considered very large storms with rotating winds. Forming over warm waters of the oceans, there are large pressure and temperature differences between the warm water and the clouds. These clouds pull the moisture and the air near the surface of the water up, towards the clouds, which creates a column of fast moving air. There are many different parts of a hurricane. Feeder Bands are squally bands of showers characterized by strong gusty winds and heavy rains. These bands become more pronounced as the storm intensifies, and are fed by the warm waters. The eye wall is a band of clouds, strong winds, and heavy rains surrounding the eye of the storm. At the eye wall, there is rapid movement of
Hurricanes are divided into 5 different categories. Category 1 is for winds that are going 74 to 95 mph, category 2 if it’s winds are 96 to 110 mph, 3 if it’s 111 to 129 mph, 4 if it’s 130 to 156 mph, and category 5 if the winds are over 157 mph. Once the winds are collected in the storm, they strengthen and enlarge
