Exam 13: Weather Forecasting

List some of the ways that you can predict the development of a surface middle latitude storm.​

An anticyclone is moving slowly eastward.Southerly winds on the western side of the system will bring warmer and more humid air to the region.Therefore,afternoon temperatures will be warmer than those of the day before.

In one forecast,west of San Francisco,the flow is meridional with a cut-off warm,upper high situated just south of Alaska.To the south,both east and west of the high are troughs.Because the shape of this flow around the high resembles the Greek letter ____,the high and its accompanying ridge are known as a(n)____ high.​

An ensemble forecast goes further and further into the future,the forecast lines can become scrambled.Such a chart is often referred to as a​

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?

Why do clouds tend to reduce temperature during the day but increase temperatures at night?​

Warm advection is most likely to occur​

Lines of equal pressure change are called ____________________.​

Describe four methods of forecasting the weather and give an example for each one.​

Describe the data and tools that a meteorologist assembles prior to making a weather forecast.

Which weather advisory is issued when falling or blowing snow and winds of at least 35 miles per hour restrict visibility to less than 1/4 mile for several hours?

The routine daily forecasting of weather by computers using mathematical equations has come to be known as ____________________.

The ____________________ is a chart that shows how one or more weather variables has changed at a station over a given period of time.​

A weather ____________________ indicates that atmospheric conditions favor hazardous weather occurring over a particular region during a specified time period.A weather ____________________,on the other hand,indicates that hazardous weather is either imminent or actually occurring within the specified forecast area.Advisories are issued to inform the public of less hazardous conditions caused by wind,dust,fog,snow,sleet,or freezing rain.

For a forecast to show skill it must

The ____________________ describes the steps used by forecasters to steer their attention from large scales to smaller scales and from short time frames to longer periods.​

How does a prog differ from an analysis?

Given a map with isallobars,high pressure systems tend to move where the isallobars indicate ____________________ values,and low pressure systems move where the isallobars are ____________________.

Which of the following can cause errors in forecasts made by numerical weather prediction models?

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