Unit 6 Weather Flashcard 2 Review

Front

What is barometric pressure?

Back

Barometric pressure is the pressure exerted by the weight of the atmosphere at a given point, typically measured in millibars (mb) or inches of mercury (inHg).

Front

What is the standard unit for measuring wind speed?

Back

The standard unit for measuring wind speed is knots, where 1 knot is equal to 1.15 miles per hour.

Front

How does air move in a low pressure system?

Back

Air in a low pressure system moves counterclockwise in the Northern Hemisphere.

Front

What is the approximate conversion of 100 degrees Fahrenheit to Celsius?

Back

100 degrees Fahrenheit is approximately equal to 38 degrees Celsius.

Front

What does a low pressure system indicate on a weather map?

Back

A low pressure system indicates areas where the atmospheric pressure is lower than surrounding areas, often associated with stormy weather.

Front

What is a high pressure system?

Back

A high pressure system is an area where the atmospheric pressure is higher than surrounding areas, typically associated with clear skies and calm weather.

Front

What is a cold front?

Back

A cold front is the leading edge of a cooler mass of air, which replaces a warmer mass of air, often resulting in precipitation.

Front

What is a warm front?

A warm front is the leading edge of a warmer mass of air, which replaces a cooler mass of air, usually bringing gradual increases in temperature and precipitation.

Front

What is the significance of millibars in meteorology?

Back

Millibars are a unit of pressure used in meteorology to measure atmospheric pressure, with standard atmospheric pressure at sea level being 1013.25 mb.

Front

What does the symbol 'H' represent on a weather map?

Back
