Hurricane Vocabulary Quiz

Trough

• An elongated area of relatively low atmosphere pressure, usually associated with a closed circulation.

• An elongated area of relatively high atmosphere pressure, usually not associated with a closed circulation.

• An elongated area of relatively low atmosphere pressure, usually not associated with a closed circulation.

• An elongated area of relatively high atmosphere pressure, usually associated with a closed circulation.

Tropical storm

• When a depression reaches sustained winds of 74 to 100 mph

• When a depression reaches sustained winds of 23 to 39 mph

• When a depression reaches sustained winds of 40 to 74 mph

• A warm core low level closed circulation with sustained winds of 23 to 39 mph

Tropical Depression

• When a depression reaches sustained winds of 40 to 74 mph

• A large high pressure system that builds over the Atlantic at the mid lattiudes

• A wind with closed circulation with winds of 40 to 74 mph

• A warm core low level closed circulation with sustained winds of 23 to 39 mph.

Storm Surge

• High surf and a rise in sea level being forced inland. Caused by winds pushing sea surfaces ahead of the storm

• High surf causing a lowering of sea level. Caused by winds pushing sea surfaces ahead of the storm

• Low seal level produced by storms

• High surf and a rise in sea level being forced inland. Caused by ocean floor tremors pushing sea surfaces ahead of the storm.

Squall Line

• A line of disturbance in the upper atmosphere.

• Thunderstorms in the atmosphere

• A line of clouds in the atmosphere

• A solid or nearly solid line or band of convection or thunderstorms

Shear

• Winds in the lower atmosphere that are beneficial to a tropical cyclone's outflow.

• Winds in the upper atmosphere that are beneficial in forming hurricanes.

• Winds in the upper atmosphere that are destructive to a tropical cyclone's outflow.

• Winds that help vertically form and build a hurricane.

Scale that divides hurricanes into strengths by categories, 1-5.

• Fujita Scale

• Saffir-Simpson Scale

• Hurricane devastation scale

• Categories 1-5

An elongated area of relatively high atmospheric pressure.

• Ridge

• Trough

• wind shear

• Dissipate

Low Pressure

• Meteorological term for clockwise circulation caused by a lowering barometric pressure. As the pressure drops lower, the winds rush in the center

• Meteorological term for counterclockwise circulation caused by a rise in barometric pressure. As the pressure drops lower, the winds rush in the center

• 31.0 inches of Hg

• Meteorological term for counterclockwise circulation caused by a lowering barometric pressure. As the pressure drops lower, the winds rush in the center

Measurement of speed

• KTS

• Millibars

• Inches of Hg

• NHC
