Maps and Models in Weather Forecasting

Flashcards covering key vocabulary and concepts related to maps and models used in weather forecasting.

Station Models

Official symbols for surface weather data shown on a map.

Constant Pressure Map

Maps showing the height of constant pressure as lines called isobars.

Ridges

Areas of high pressure showing upcurved isobars, usually associated with fair weather.

Troughs

Areas of low pressure showing downcurved isobars, usually associated with inclement weather.

Numerical Weather Prediction (NWP)

Computer generated maps that use weather data to predict weather patterns and forecasts.

Isobars

Lines on a map that connect points of equal atmospheric pressure.

Weather Symbols

Icons representing various weather conditions like rain, snow, and wind on station models.

Air Flow

Movement of air in the atmosphere affecting weather patterns and forecasting.

Forecasting

The process of predicting future weather based on current atmospheric data.

Dew Point

The temperature at which air becomes saturated and water vapor begins to condense.

Pressure Trend

The change in atmospheric pressure over time, represented in millibars (mb).
