Weather vs. Climate Vocabulary Weather-daily or hourly changes in the Climate-usual weather in a long period of time in a place. Climate is the usual weather so it affects every day weather North Carolina has a subtropical climate. There are many different types of climates such as tropical ,polar and desert. 9/21/2018

Water Cycle

Weather

The water cycle and weather Water is necessary to all life on Earth. Every part of the water cycle influences Weather. The water cycle controls the Distribution of water on earth and in the atmosphere. Clouds and precipitation Are evidence of water moving through The water cycle.

The water cycle and climate The water cycle also shapes climates around the world. Precipitation or water in that falls from the clouds is one of the ways people classify climate .The average precipitation In a region tells us what type of climate it . The water cycle creates reservoirs to store water . The Ocean is a good example .

Weather patterns

FRONTAL BOUNDARIES Vocabulary Air Masses-a large body of air with only small horizontal variations of temperature, air pressure and moisture. Front-the interface between air masses of different temperatures or densities . Changes in the weather happen as different air masses move through a region. Something you may not realize is that fronts not only extend in the horizontal direction but in the vertical as well.

Warm fronts and Cold fronts A warm front is the transition zone where a warm air mass is replacing a warmer air mass . On a weather map a warm front is represented by a solid line with triangles point to the warmer air. Cold Front Is the transition where a cold air mass is replacing a warmer air mass. On a weather map a cold front is represented by a solid line with semi-circles.

Weather Map

Temperature Temperature tells us if the air is warm or cold. Density is the amount of matter in an object. The density of the air depends of it temperature. Temperature is influenced by cloud cover.

Air pressure is the weight of the air above the Earth's surface. High pressure occurs when the air pressure is greater than the surrounding area. High pressure usually means dry weather and cooler temperatures. Low pressure occurs when the air pressure is lower than surrounding areas. Low pressure usually means wet weather and warmer weather.

. Did you know tornadoes are edible?

Wind

Clouds Clouds are water droplets or ice crystals in the air . They play a major role in weather. They have an influence in the temperature and bring different types of precipitation . The four different types of precipitation are rain,snow,sleet and hail . Clouds commonly form at frontal boundaries and around areas of low pressure .Clouds also block radiation form the Sun. This influences temperatures.

Types of precipitation

Precipitation Precipitation is a solid or liquid water that falls from a cloud to the surface of the earth. Precipitation is likely when two different air masses meet at a frontal boundary. High humidity also increases chance of precipitation .

Weather data builds climate records

Weather builds climate records Scientists need a lot of data to predict weather. Trends are patterns in weather . They show consistent changes in the weather . This makes forecasting easier. Trends in weather tell us about climate. A climate Record is a historical record of weather data for a specific region.
