Exam 12: Weather Analysis and Forecasting

-The current sea level air pressure represented on the station model shown above is:

One commonly used way to improve a numerical model forecast is to:

Nowcasting is heavily dependent on weather radar and geostationary satellites.

In determining the occurrence of precipitation,the NWS forecasts are correct more than ________ percent of the time.

List three characteristics that are used to identify the location of a front on a synoptic weather chart.

This type of weather forecasting uses physical models of the atmosphere: ________.

Synoptic charts have isobars plotted at ________ millibar intervals.

Your local weather forecast is most likely provided by the (a):

In order to demonstrate true skill,a forecast must do a better job than a climate-based prediction.

These satellites circle the earth in a north-to-south direction,and obtain images of the entire Earth twice a day by drifting about 15 degrees westward over the earth's surface during each orbit.

The current conditions in your location are sunny with a temperature of 85°F.Based on these observations,you forecast that in a few hours,it will be sunny with a temperature in the mid 80s.What kind of forecast have you issued?

In the United States,the governmental agency responsible for gathering and disseminating weather-related information is the:

An ensemble forecast is produced by:

Geostationary satellites are usually centered over one pole.

Observing and forecasting small,short lived weather events (such as a thunderstorm)is strongly dependent on radar.

When upper-air flow produces large-amplitude troughs and a general ________ flow,cold air moves southward and cyclonic activity dominates the weather.

A wave pattern in the upper-level winds at middle latitudes provides for:

Which of the following data is not plotted on a weather chart?

You'd like to plan a Christmas day flight to visit family.You have several months lead time.How might you determine the probability of snowfall occurring and potentially interfering with your travel plans?

Infrared images provide a way to determine which clouds are more likely to produce what?
