Anyhow, Natural disasters occur everywhere around the world every single day, if they are small or large. Natural disasters events have been a topic that has affected many countries through the years. On top of that, the weather can turn bad, quick. Rain seems to come out of nowhere, even during a nice and sunny day. Just these past few months, Florida faced a. Logistics Clusters Delivering Value and Driving Growth A fundamental part of society since the beginning of time has been the trade of information, cash, and physical goods between at least two separate parties.
Whether it is amongst consumers, businesses, or between a business and a consumer, it has always existed in some form. As time passes, our knowledge and technology have advanced therefore creating a stronger supply chain process. The intensity of tornadoes is measured on the Fujita Scale see Table below , which assigns a value based on wind speed and damage.
Cyclones can be the most intense storms on Earth. A cyclone is a system of winds rotating counterclockwise in the Northern Hemisphere around a low pressure center. The swirling air rises and cools, creating clouds and precipitation. There are two types of cyclones: middle latitude mid-latitude cyclones and tropical cyclones. Mid-latitude cyclones are the main cause of winter storms in the middle latitudes. Tropical cyclones are also known as hurricanes. An anticyclone is the opposite of a cyclone.
Air comes in from above and sinks to the ground. High pressure centers generally have fair weather. Mid-latitude cyclones , sometimes called extratropical cyclones, form at the polar front when the temperature difference between two air masses is large.
These air masses blow past each other in opposite directions. Coriolis Effect deflects winds to the right in the Northern Hemisphere, causing the winds to strike the polar front at an angle. Warm and cold fronts form next to each other.
Most winter storms in the middle latitudes, including most of the United States and Europe, are caused by mid-latitude cyclones Figure below. A hypothetical mid-latitude cyclone affecting the United Kingdom. The arrows point the wind direction and its relative temperature; L is the low pressure area. Notice the warm, cold, and occluded fronts. The warm air at the cold front rises and creates a low pressure cell. Winds rush into the low pressure and create a rising column of air.
The air twists, rotating counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Since the rising air is moist, rain or snow falls. Mid-latitude cyclones form in winter in the mid-latitudes and move eastward with the westerly winds.
These two- to five-day storms can reach 1, to 2, km to 1, miles in diameter and produce winds up to km 75 miles per hour. Like tropical cyclones, they can cause extensive beach erosion and flooding. Figure below. Tropical cyclones have many names. By any name, they are the most damaging storms on Earth.
The warm seas create a large humid air mass. The warm air rises and forms a low pressure cell, known as a tropical depression. Thunderstorms materialize around the tropical depression.
As the air rises, water vapor condenses, releasing energy from latent heat. If wind shear is low, the storm builds into a hurricane within two to three days.
Hurricanes are huge with high winds. The exception is the relatively calm eye of the storm where air is rising upward.
Rainfall can be as high as 2. The release of latent heat generates enormous amounts of energy, nearly the total annual electrical power consumption of the United States from one storm.
Due to the conflicting air masses, high winds develop and storms can erupt, sometimes turning into full-blown blizzards. Difference between Hurricane and Blizzard. Key Difference: A hurricane is tropical cyclone that is characterized by thunderstorms, strong winds and heavy rains.
Whereas, a blizzard is a winter bound storm, which is mainly caused by strong continued winds. Comparison between Hurricane and Blizzard: Hurricane Blizzard Definition A hurricane is also known as a tropical cyclone.
Composition Moist air, water Snow, wind Shape Closed, circular fluid motion. Types Hurricane is a type of cyclone Blizzard is type of snowstorm, but both are extremely different from each other. Speed Wind speed of 74mph to over mph Wind speed of 35mph to over 45 mph Rotation Clockwise in the southern hemisphere and counterclockwise in the northern hemisphere There is no particular rotation Scale for Measurement Saffir-Simpson Hurricane Wind Scale There is no scale for measuring blizzard severity.
How are they formed Warm low-pressure air rises, while cold high-pressure air moves underneath it. Life Days Days, weeks or months. Image Courtesy: boston. Comments Thank you so much.
