What is Weather?
[]

1. weather is the condition of the atmosphere at a particular time and place. 2. air, sun, water and the earths movement.

Weather vs Climate
__ [] __

3. climate is what you expect and weather is what you get.

Air Pressure
__ [] __ 4. Complete the following chart:
 * || ==== **High Pressure** ==== || ====** Low Pressure **==== ||
 * Air movement (up or down) || up || down ||
 * Temperature of air || ​warm || ​ cold ||
 * Wind movement at ground || ​ happy highs || ​ lousy lows ||
 * Expected weather || good || ​ bad ||

** Clouds **
|| **Understanding Basic Concepts** - explain the formation of clouds and the effects of different cloud formations on weather and climate ||


 * Use this web site to answer the following questions. **
 * [] **

1. ** Clouds are a visible mist of billions of water and ice particles floating in the sky. ** 2. ** Clouds form when air cools below its saturation point and causes water vapor to condense into tiny water droplets. ** 3. ** CIRRUS means 'curl of hair', CUMULUS means 'heap', and STRATUS means 'layer'. ** 4. Follow the links to learn about each type of cloud and then complete the table on the next page. To help you identify clouds, download, print and construct the following "Cloud Key".

**Forecasting**
|| **Understanding Basic Concepts** -recognize large-scale and local weather systems - predict local weather patterns using data from their own observations of weather and from weather reports - identify patterns in air movement ||

The following questions and organizers will help you keep track of the crucial information you’ll need.
 * Read the details at [] and follow the links.**

Cloud Forecasting

 * **Cloud Type** || **Description** || **Possible Weather** ||
 * cirrus || Thin, Wispy || good weather, no precipitation ||
 * altocumulus || fuzzy bubbles in long strings or rows || cold front is coming ||
 * nimbostratus || dark, low hanging || light, moderate precipitation ||
 * cumulus || big cotton balls || no rain ||
 * cumulonimbus || tall, wide || tunder, lightening, heavy rain ||

Wind Forecasting
What can make the above predictions inaccurate? answer: if there is a large body of water
 * **Wind Direction** || **Possible Weather** ||
 * North || cool, dry weather ||
 * South || warm weather ||
 * East || a variety of things ||
 * West || a variety of things ||

Senses Forecasting
What might you hear that can help you forecast the weather? answer: thunder or wind

Write the capital letter A or B at the end each sentence. A = Cold Front B = Warm Front 1. Cool air mass - warm air mass moves in. B 2. Warm air mass - cool air mass moves in. A 3. Brings gentle rains that may last for hours or days. B 4. Strong winds are formed followed by heavy rain, crashing thunder, and flashing lightning.A 5. When the front passes, the temperature warms up and it becomes humid. B 6. When the front passes, the weather turns cooler. B 7. Farmer Brown prefers this type of front. B 8. Usually happens and is over with quickly.A
