**The Elements of Weather**
|| **Understanding Basic Concepts** - explain the difference between weather and climate and the factors that influence both of these systems The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time. - identify patterns in air movement Wind Pattern.

- identify the effects of air pressure
 * Air pressure** is the force exerted on you by the weight of tiny particles of air (air **//[|molecules]//**). Although air molecules are invisible, they still have weight and take up space. Since there's a lot of "empty" space between air molecules, air can be compressed to fit in a smaller **//[|volume]//**. ||

What is Weather?
[]


 * 1.** Define weather- The weather is the condition of the atmosphere or changes in the atmosphere at a particular time and place.

2. What four factors affect weather...
 * ** the air **
 * ** the sun **
 * ** water **
 * **the earth's movement**

1.What are clouds? 2. Explain how clouds form. 3. What are the 3 "families" of clouds and what do their Latin names mean? 4. Follow the links to learn about each type of cloud and then complete the table on the next page.
 * Clouds are a visible mist of billions of water and ice particles floating in the sky. **
 * Clouds form when air cools below its saturation point and causes water vapor to condense into tiny water droplets. **
 * There are three families of clouds: cirrus, cumulus, and stratus. These are the latin names given to clouds in 1804. Cirrus means 'curl of hair', cumulus means 'heap', and stratus means **

To help you identify clouds, download, print and construct the following "Cloud Key". [] After completing the chart, you could try a Cloud Quiz at; [] 

The following questions and organizers will help you keep track of the crucial information you’ll need.

Cloud Forecasting

 * **Cloud Type** || **Description** || **Possible Weather** ||
 * cirrus || High level, wispy, hair-like, white tufts, or filaments. Higher than mountains || no storm ||
 * altocumulus || Middle level layered cloud, rippled elements, generally white, sky showing through. || no storm ||
 * nimbostratus || Thicker and darker than stratus, dark grey along base, foggy. || possibley a storm ||
 * cumulus || Low level, individual cells, puffy, like lumps of cotton, flat bases. || no storm ||
 * cumulonimbus || Low level, very large cauliflower-shaped or anvil-shaped tops. Thunderstorms, lightning, rain and tornadoes. || storm ||

What can you make the above predictions inaccurate? they could change easily and sometimes they can either be wrong or right.

Senses Forecasting
What might you hear that can help you forecast the weather? you could watch the news, go outside, or look it up on the internet or newspaper.

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.-A 6. When the front passes, the weather turns cooler.-B 7. Farmer Brown prefers this type of front.- B 8.
