Use the data on the weather map from July 4, 2006 to create a weather map and a weather forecast for the next day. Include the locations of fronts, highs, lows, and precipitation.
Use these forecasting tips to create the weather maps:
• If there is a lot of water vapor in the air and a cold front is approaching, precipitation is most likely on its way, too.
• A change in air pressure means there will most likely be a change in weather. Falling air pressure generally means rain. Rising air pressure generally means clearing skies.
• Air masses and fronts generally move west to east.

Use these tips to create a written forecast:
• Write as if you are a weather forecaster explaining the forecast to a viewing audience.
• Explain the weather maps.
• Describe changes in pressure, temperature, and precipitation.

1. What was most challenging about forecasting the weather?

2. How did this project prepare you to be a real meteorologist?

3. What do you need more practice doing before you are promoted to entry-level meteorologist?

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
