Weather Part 2

Front

What is a cyclone?

Back

A cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure, characterized by inward spiraling winds.

Front

What is an anticyclone?

Back

An anticyclone is a weather phenomenon characterized by high atmospheric pressure, where air descends and spreads outward, leading to clear skies.

Front

What is the main difference between cyclones and anticyclones?

Back

The main difference is the direction of their winds: cyclones have winds that rotate counterclockwise in the Northern Hemisphere, while anticyclones have winds that rotate clockwise.

Front

What does barometric pressure measure?

Back

Barometric pressure measures the weight of the atmosphere above a given point, typically expressed in millibars (mb) or inches of mercury (inHg).

Front

What is the standard atmospheric pressure at sea level?

Back

The standard atmospheric pressure at sea level is 1013.25 mb.

Front

How does temperature affect the capacity of air to hold water vapor?

Back

As air temperature increases, its capacity to hold water vapor also increases.

Front

What is relative humidity?

Back

Relative humidity is the ratio of the current amount of water vapor in the air to the maximum amount of water vapor the air can hold at that temperature, expressed as a percentage.

Front

What is dew point?

Back

Dew point is the temperature at which air becomes saturated with moisture and water vapor begins to condense into liquid.

Front

How do you calculate dew point from dry bulb temperature and relative humidity?

Back

Dew point can be estimated using tables or formulas that relate dry bulb temperature and relative humidity.

Front

What is a station model in meteorology?

Back

A station model is a symbolic representation of weather data for a specific location, including information like temperature, pressure, wind direction, and precipitation.
