Exam 12: Weather Analysis and Forecasting

Long- range forecasting employs this method: ________.

One of the major problems of global weather forecasting is the lack of cooperation between major world powers.

If you need to measure wind speed and direction at a height of 10 km above the surface, the type of radar you would use is called:

Larger north- south temperature contrasts occur in summer.

The gas laws are applied in this method of weather prediction:________ .

"Partly cloudy skies" is an example of a qualitative forecast.

Successful short term forecasts (a few hours) can often be made using this method of prediction.

These types of images are views of the earth the way an astronaut would see our planet from space.

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

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 accuracy of day- to- day weather forecasts for periods beyond__________ day(s) is relatively unreliable.

One of the primary uses for a 500- mb map is:

All satellites have the disadvantage that their orbits place them very far (over 20,000 miles) above the earth.

Infrared imagery, like visible imagery, can only detect the presence of clouds during the day.

What is a typical time- step for a numerical weather model?

Which of the following is responsible for collecting and assimilating weather data from across the globe?

Satellites have made ground- based weather stations almost obsolete.

Sharing of weather data among nations around the world is very limited.

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?

The development of large, fast computers has allowed this method of weather prediction to become useful.
