1. Weather Forecasts

2. Biblical Reference I would hurry to my place of shelter, far from the tempest and storm. Psalm 55:8

3. Measuring the Conditions is the first step to making a weather forecast. Instruments: –Temperature – Thermometer –Air Pressure – Barometer –Relative Humidity – Psychrometer –Wind Speed – Anemometer Measuring the Weather

4. Surface Report: Describes a set of weather measurements made on the Earths surface. –Temperature, Air Pressure, Humidity, Precipitation, Wind Speed & Direction, Cloud Cover and Visibility Upper-Air Report: Describes a set of weather measurements above the Earths surface. –Wind, Temperature and Humidity –Weather Balloons with Radiosonde make reports twice a day in hundreds of locations. Surface and Upper-Air Reports

5. Satellite images are used for seeing cloud patterns and movements –Example: Tracking a Hurricane Radar images can be used to detect cloud cover, rainfall or storm location, intensity, and movement, as well as the potential for severe weather –Doppler Radar: A specialized type of radar that can detect precipitation and the movement of small particles to determine wind speed. Satellite and Radar Images

6. Satellite Image Radar Image Doppler Radar Image

7. Weather maps use symbols and images to describe the weather over a certain location. There are six basic types of Weather Maps: –Satellite –Radar –Precipitation –Temperature –Wind speed –Front Weather Maps

10. Station models from specific locations provide information that can be used to predict weather patterns. Information found on a station model can include: Station Models

11. A station model uses observations from surface reports and upper-air reports

12. Isobars are lines that connect all places on a map where pressure has the same value. –Isobars show high and low pressure areas –Winds are stronger when isobars are close together –Isobar comes from the Greek, isos, which means equal; and baros, which means heavy Isotherms are lines that connect places with the same temperature. Mapping Temperature & Pressure

13. Precipitation Maps

14. Temperature Maps

15. Wind Speed Maps

16. Front Maps

24. Computer Models, which solve complex math formulas, are used to predict: –Temperatures –Wind Speeds –When & Where it will Rain –Types of Clouds Meteorologists use the Internet to share information Predicting the Weather Harry Reigns

25. What about Weather Folklore? Onionskin is very thin, mild winter is coming in. Onionskin is thick and tough winter will be cold and rough. Rain before seven, quit by eleven. Clear moon, frost soon. Weather Folklore
