801 Spring Vacation Homework-
Weather Lab- You must work on this almost everyday!!!!
Create a chart and find information from either the Newspaper or online that reports the following...
Date, Termperature High, Temperature Low, Wind Speed, Wind Direction, Barometric Pressure (in millibars), Dew point Temperature, Relative Humidity, % Cloud cover, Precipitation if any (type, amount, how long)
The chart must have at least 7 entries for 7 different days of the vacation
Then Graph the average temperatures with 1 line, barometric pressure with another and wind speed with another.
Notice trends..... Use this information and write a prediction for the day we come back from break. What information allowed you to make this prediction?

Temperature-
Two cycles control the earth’s temperature: the daily weather cycle and the seasons. Temperature is usually lowest in the morning and warmest in mid afternoon. Clouds reduce daytime temperature by reflecting sunlight back toward space. At night clouds help hold heat energy to Earth.
We measure temperature by actually measuring the vibration of molecules in the atmosphere. The warmer air vibrates more than colder. Mercury in the thermometer expands when it is heated and thins when it is cooled. Temperature is measured by Fehrenheith, Celsius and Kelvin.
Air Pressure-
Air Pressure is caused by the weight of the atmosphere. It is measured by a barometer with millibars. The millibar and inch table can be found in your ESRT.
Factors that affect Air Pressure
Altitude- it decreases with altitiude because as air rises there is less
Pressure pushing downward
Temperature- Cold air is more dense- therefore pressure rises
Warm air is less dense and pressure decreases
Humidity-
When water evaporates into the atmosphere, the air must
Expand to accept it- this moves nitrogen in the atmosphere
As a result, the heavy nitrogen particles are replaced by lighter vapor molecules
and pressure decreases as humidity Increases.
Moisture- When there is too much water vapor in the air it is saturated.
Dew Point- the temperature in which the air must be
Cooled to become saturated. If the temperature
Falls below the dew point, condensation occurs
And vapor changes to liquid.
Measure Moisture-
A sling psychometer is used to measure dew point. It is two
Thermometers with wet bulbs and dry bulbs on the end (see
Picture in mcguire book) The bulbs are called wicks and to
Find dew point you need to find the difference between them
And use the chart in the ESRT to compare.
Relative Humidity-
Compares how much moisture is actually in the air to how
Much could be in the air if it was saturated. It is expressed as
A percentage.
Wind-
Wind is the natural movement of air along the Earth’s surface. Wind moves from cold to hot, due to the fact that it is simply air pressure making room for air. So since cold air has is generally more dense and has high pressure it will move to areas of low pressure (warm air). Fastest winds blow where gradient between Isobars (air pressure) is the greatest.
