Forecasting Weather
Target #32- I can summarize how global weather is monitored
• Weather forecasting began in the mid 1800’s when basic tools, like the thermometer and barometer, were
invented
• Global Weather Reporting
• Weather observations at stations _______________________________________________
• Records temperature and pressure every ________________________________________
• Also measure precipitation, surface wind ____________________________________________,
and the type and amount of ________________________________________.
• World Weather Watch
• A program designed to promote the ________________________________________________
______________________________________________________
• Helps developing countries establish or improve their meteorological services
• Offers advice on the _______________________________________________ on natural
resources and on human activities
Target #33- I can explain the function of a weather map
• All data collected is transferred to weather maps
• Allows meteorologists to understand the _________________________________________ and to
___________________________________ future weather events
• Uses symbols and colors to indicate certain characteristics
• Station model:
•
Examples of data used
• Cloud cover
• Wind speed & direction
• Types of precipitation
• Storm activity
• Air temperature
• Dew point
Target #34- I can interpret the data shown in a station model
Practice Problem#1
Practice Problem #2
Target #35- I can explain how isobars are used to indicate patterns in weather
• Scientists use lines on weather maps to __________________________________________________________
_______________________________________________________.
• Lines that connect points of equal ______________________________________________________ are
called ______________________________
• Lines that connect points of equal _________________________________________________________
are called ________________________________
• The spacing and shape of the isobars help meteorologists interpret their observations about the speed and
direction of wind
• __________________________________________________ bars indicate a ______________________
change in pressure and high wind speeds
• __________________________________________________ isobars generally indicate a
_____________________________ change in pressure and low wind speeds
• Isobars that form __________________________ indicate centers of high or low air pressure
• Marked with an __________ (high) or an ____________ (low)
Target #36- I can draw and interpret isobars and isotherms on a map
Target #37- I can interpret the weather patterns illustrated in a weather map
• Weather maps are used to illustrate many different features
• __________________________________
• Highs and lows in pressure
• __________________________________
• Warm, cold, occluded, stationary
• _________________________________
• Precipitation
• Direction of air flow
