Flashcards
Blizzard
Blizzard
A severe winter storm with high winds, heavy snowfall, and limited visibility, lasting for hours or days. Extremely low temperatures combined with strong winds create hazardous conditions.
Hurricane
Hurricane
Powerful storms forming over warm ocean waters, characterized by strong winds, heavy rainfall, and a central eye of calm conditions.
Storm
Storm
A meteorological event involving the movement of air masses, typically extracting energy from the environment, such as warm ocean waters for hurricanes.

Study Notes
Types of Storms
- Storms are atmospheric disturbances characterized by strong winds, precipitation, and often, other severe weather phenomena.
- Various types of storms exist, categorized by their characteristics and intensity. These include thunderstorms, tornadoes, hurricanes (typhoons in the western Pacific), and blizzards.
- Thunderstorms form when warm, moist air rises rapidly, leading to condensation and the release of latent heat.
- Tornadoes are violently rotating columns of air that extend from a thunderstorm cloud to the ground. They form due to the interaction of wind shear and unstable atmospheric conditions.
- Hurricanes (typhoons) are large, rotating storms that form over warm ocean waters and are characterized by strong winds, heavy rain, and storm surges.
- Blizzards are severe winter storms characterized by high winds, heavy snowfall, and low visibility.
Thunderstorms
- Thunderstorms are characterized by the presence of lightning and thunder.
- They often cause heavy rainfall, hail, and strong winds.
- The life cycle of a thunderstorm typically consists of three stages: cumulus, mature, and dissipating.
- The cumulus stage involves the initial formation of the cloud.
- The mature stage is when precipitation and downdrafts appear.
- The dissipating stage occurs as the storm weakens.
- Thunderstorms can produce severe weather, including large hail and damaging winds, as well as flooding.
Tornadoes
- Tornadoes are rapidly rotating columns of air that extend from a cumulonimbus cloud to the ground.
- They are often associated with supercell thunderstorms.
- They are characterized by high wind speeds and significant damage potential.
- Different strengths of tornadoes are defined on the Fujita scale (and later, the Enhanced Fujita scale).
- Tornadoes can occur anywhere but are most frequent in the central US "tornado alley."
- Warning systems exist to alert people about impending tornadoes, usually through weather reports and sirens.
Hurricanes (Typhoons)
- Hurricanes are intense tropical cyclones with sustained winds of at least 74 mph.
- They form over warm ocean waters and derive energy from the evaporation of water.
- Hurricanes have distinct storm structures: eye, eye wall, rain bands.
- The eye is a relatively calm area at the center of the storm.
- Storm surge is a major hazard, resulting in flooding of coastal areas.
- Damage from hurricanes is measured by the Saffir-Simpson Hurricane Wind Scale.
- Hurricanes can cause widespread damage to coastal communities, infrastructure, and agriculture.
Blizzards
- Blizzards are severe winter storms that feature high winds, heavy snowfall, and reduced visibility.
- These storms often last for several hours or even days.
- The combination of extremely low temperatures and very strong winds creates extremely dangerous conditions.
- In addition to the hazards of drifting snow and reduced visibility, there is the risk of hypothermia and frostbite.
- Strong winds can cause power outages and make travel extremely difficult or dangerous.
Common Characteristics of Storms
- All storms involve the movement of air masses.
- All storms extract energy from their environment, such as from the warm ocean water for hurricanes.
- Most storms involve some form of precipitation, be it hail, rain, or snow.
- Each storm type has specific environmental conditions that allow for development.
- They can cause significant damage to property, infrastructure and human life, depending on their intensity and duration.
- Forecasting technology plays a vital role in predicting and preparing for storms.
