Types of Weather

Blizzard: Heavy Snow, ice, Cold Temperatures
Blizzard: Heavy Snow, ice, Cold Temperatures

Ground blizzard refers to a weather condition where loose snow or ice on the ground is lifted and blown by strong winds. The primary difference between a ground blizzard as opposed to a regular blizzard is that in a ground blizzard no precipitation is produced at the time, but rather all the precipitation is already present in the form of snow or ice at the surface.

Cold Wave
Cold Wave

A cold wave (known in some regions as a cold snap or cold spell) is a weather phenomenon that is distinguished by a cooling of the air. Specifically, as used by the U.S. National Weather Service, a cold wave is a rapid fall in temperature within a 24-hour period requiring substantially increased protection to agriculture, industry, commerce, and social activities.

Cyclone (Generic) Arctic Cyclone
Cyclone (Generic) Arctic Cyclone

A tropical cyclone is a generic term used by meteorologists to describe a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation.

Derecho Storms
Derecho Storms

At night, keep the volume turned up, so you can hear these crucial severe weather warnings. On June 29, 2012, an infamous derecho slammed a 700-mile swath from the Midwest to the mid-Atlantic. Washington, D.C., was among the cities hit hard by the derecho. Millions of people were without power for a week or more due to the widespread damaging wind gusts, which were higher than 80-90 mph in several communities.

Dust Storm: Strong Winds, Arid Conditions
Dust Storm: Strong Winds, Arid Conditions

Meteorological conditions play a big role in determining the size, duration, and intensity of dust storms. Weather patterns can be broadly categorized into two categories: large-scale -- or synoptic -- weather systems, and smaller patterns known as mesoscale systems.

Flood: Heavy Rainfall
Flood: Heavy Rainfall

what is flash flooding? Flooding that begins within 6 hours, and often within 3 hours, of the heavy rainfall (or other cause). Flash Floods can be caused by a number of things, but is most often due to extremely heavy rainfall from thunderstorms.

Flash Flood Guidance. Flash Flood Guidance is an estimate of the amount of rainfall required over a given area during a given duration to cause small streams to flood issued by Northeast River Forecast Center.

Fog
Fog

Sometimes fog forms when warm air moves over a cold surface. Warm air moving over snow-covered ground in winter and sea fog drawn inland over a cool land surface along the West Coast are two prime examples of so-called advection fog. Unlike radiation fog, advection fog can sometimes be seen as moving laterally along or near the ground.

Hail Storms
Hail Storms

Hail is a form of frozen precipitation that's created by strong thunderstorms with fast updrafts — air being pulled upward into a thunderstorm. It can cause serious damage, especially to cars, aircraft, glass-roofed structures and most notably, farmers' crops.

Heat Wave
Heat Wave

A heat wave is a period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is measured relative to the usual weather in the area and relative to normal temperatures for the season.

Hurricanes
Hurricanes

"Hurricane Season" begins on June 1 and ends on November 30, although hurricanes can, and have, occurred outside of this time frame. NOAA's National Hurricane Center predicts and tracks these massive storm systems, which occur, on average, 12 times a year in the Atlantic basin.

3. Ice Storms and Their Impacts Can Last For Days. Depending on the severity of the ice storm and the weather pattern, impacts can persist for days. If more than a half-inch of ice occurs and damage is widespread, it can take quite a while to remove trees and repair power lines. This can result in a loss of electricity and heat for several days.

Lightning
Lightning

All lightning is dangerous, but cloud-to-ground lightning is the most dangerous type of lightning. Most cloud-to-ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below.

Severe Thunderstorm (Hailstorm, Downburst: Microburst/Macroburst)
Severe Thunderstorm (Hailstorm, Downburst: Microburst/Macroburst)

What Is a Downburst? A downburst is an area of strong, downward moving air associated with a downdraft from a thunderstorm. As the downdraft impacts the ground, the air is forced outwards in all directions while it also curls backwards.

Windstorm (Gradient Pressure Induced)

These differences in barometric pressure are what create the pressure gradient force and wind as air constantly moves between areas of high and low pressure. To show wind speeds, the pressure gradient is plotted onto weather maps using isobars mapped between areas of high and low pressure.
