Exam 14: Weather Forecasting

The greatest improvement in forecasting skill during the past 30 years has been made in forecasting severe storm warnings for hurricanes and tornadoes.

Which of the following is presently a problem with modern-day weather predictions?

Smaller grid spacing in numerical weather prediction models typically leads to:

A prog is a chart that interprets the current state of the atmosphere.

A weather warning indicates that:

List some of the factors that affect the accuracy of atmospheric models.

For a forecast to show skill it must:

Explain how observed teleconnection patterns can help in the preparation of a seasonal weather forecast.

Weather forecast that predicts that the future weather will be the same as the present weather is called a persistence forecast.

Warm advection is most likely to occur:

What local signs would you look for to predict the approach of a low pressure center or a weather front?

Modern computer forecasting models with very small grid spacing can only resolve large-scale features like jet streams and large highs and lows.

A forecast of an extended period of dry weather would be made for a region beneath:

A "forecast based on weather types" is a forecasting technique that produces several versions of a forecast model,each beginning with slightly different weather information to reflect errors in the measurements.

Assuming you know last night's minimum temperature,what weather information would you use to predict tonight's minimum temperature?

An analysis is:

Wintertime CAPE values tend to be much larger than summertime values.

If you wanted to make a persistence forecast of minimum and maximum temperatures for a particular city,which type of chart would be most helpful?

A persistence forecast could be quite accurate when:

Low 1000-500 mb thicknesses correspond to cold air,while high thicknesses correspond to warm air.
