Weather Reminder Charlie, Kevin, and Wade

Weather Definition: The state of the atmosphere in a certain place and time that regards to heat, sunshine, rain, wind, etc. Weather is also more specific and exact. Not to be confused with climate weather takes place over shorter periods of time and is more localized.

To make it clear Weather would cover a tornado in a city or a hurricane over the ocean or even a cold front moving towards your town. While climate would cover a whole biome like a tundra or a desert over a long period of time.

Helpful vocabulary Heat: Transfer of energy Air Pressure: The weight of the atmosphere pushing down on the earth's surface, force is 1 Bar. Dew Point: moisture in the air cooled to this temp will form water droplets. Wind: energy traveling through the air by waves caused by uneven heating of the earth's crust by the sun.

Weather systems A weather system is a large area of the atmosphere that has special temperature and moisture conditions. Uneven distribution of solar energy produces global circulation patterns. This causes weather fronts.

Cold fronts Cool dry air moving from west to east, goes under warm fronts.

Warm fronts Low pressure system usually accompanied by light rain and high humidity.

Weather maps Definition: They are maps that show the state of weather across a large area. Information: Weather maps have been used since the mid- 19th century, and they are important because they help with research and forecasting the weather.

Weather station models

Higher pressures Tend to be followed By nice weather and Lower pressures tend To be followed by Nastier weather.

Definition: A complex series of climatic changes that occurs every few years, and affects the equatorial Pacific region. Causes: El Nino usually causes the eastern equatorial region to have severe droughts, but on the western equatorial region it causes flooding.

Definition: A climate pattern that describes the cooling of surface ocean waters along the tropical west coast of South America and it is often considered to be the counterpart to El Nino.

Hurricanes Hurricanes are measured by the SS-scale When the wind speed of a tropical weather storm reach 74 mph it's a… Hurricane The season starts june 1st and end on november 30th… but hurricanes can occur outside of the season. Starts out over water. Generally occurs in more tropical regions.

Tornado Spinning columns of air formed by a cold front and a warm front meeting Creating a low pressure system that creates strong wind that can rip appart houses and lift cars. The EF scale is what America uses to measure them. EF3 is when the cool stuff begin and it only goes up to EF5.
