Question

A. A forecast that is the average of a set of forecasts is a ___________________ forecast.

B A tornado over water is called a _________________.

C The El Nino Southern Oscillation includes a regime called ______________ where colder water accumulates along the west coast of North and South America.

D. When hurricanes approach land and make landfall, they produce a _________________ that causes severe flooding in low-lying coastal areas.

E. A hurricane is a tropical cyclone with winds of _______ mph or higher.

26. Tropical cyclones don’t form along the equator because the ____________ force is

never strong enough

F. The _____________________ scale is used to measure Hurricane Intensity.

G. A ___________   line can often be produced by a cold front progressing into warm, moist mT air. It often moves well in advance of the cold front as an organized group of multicell thunderstorms

H. Tropical Storms form from a Tropical _______________ which features the first completely closed cyclonic tropical circulation with winds up to but not over 33 knots.

I. Doppler Radar technology has saved lives by increasing the lead time for ____________ warnings thanks to ability to detect rotation in a thunderstorm.

Answer 1

A. A forecast that is the average of a set of forecasts is a moving average forecast. The moving average method provides future projections based on the average of a specific set of historical data.

B. A tornado over water is called a waterspout which appears as a rotating vortex of clouds.

C. The El Nino Southern Oscillation includes a regime called La Nina where colder water accumulates along the west coast of North and South America. During La Nina phase, the sea surface temperatures are relatively cooler in the Eastern and Central tropical Pacific Ocean.

D. When hurricanes approach to land and make landfall, they produce a storm surge that causes severe flooding in low-lying coastal areas. A rise in sea level occurs during a storm surge due to changing winds and pressure conditions.

E. A hurricane is a tropical cyclone with winds of 74 mph or higher. A category-1 has a minimum sustained wind speed of 74 mph.

F. The Saffir-Simpson scale is used to measure Hurricane Intensity based on sustained wind speeds.

G. A squall line can often be produced by a cold front progressing into the warm, moist maritime tropical air mass. It often moves well in advance of the cold front as an organized group of multicell thunderstorms.

H. Tropical Storms form from a Tropical Depression which features the first completely closed cyclonic tropical circulation with winds up to but not over 33 knots. The range of maximum surface wind speed in deep depressions is 17 to 33 knots.

I. Doppler Radar technology has saved lives by increasing the lead time for tornado warnings thanks to the ability to detect rotation in a thunderstorm.
