Exam 12: Weather Analysis and Forecasting

Satellites have made ground-based weather stations almost obsolete.

Long-range forecasts estimate temperature and precipitation only.

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

Despite advances in computer technology,numerical weather prediction has advanced little since 1960.

-What is the current wind direction represented on the station model shown above?

The polar jet stream migrates southward in winter and northward in summer.

________ weather forecasting is an area that relies heavily on statistical averages obtained from past weather events (climatic data).

Nowcasting:

Which technique is used that attempts to match current conditions with similar well established patterns from the past?

The word synoptic literally means:

Until the late 1950s,synoptic weather forecasting with hand-drawn charts was the primary basis for making weather predictions.

The acronym NOAA stands for:

Long-range forecasting employs this method: ________.

Pacific storms move toward Alaska more during the cold months than the warm months.

Which of the following upper air maps is most useful for observing the details of the polar jet stream?

Clouds and precipitation patterns are often clues to the position of a front.

The process of predicting the future state of the atmosphere is called:

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

Smaller north-south temperature contrasts are associated with slower jet stream flow.
