Weather (Air masses)

A huge body of something that has basically the same temperature and amount of moisture throughout.

NGSS.MS-ESS2-6

Thin, wispy cloud composed of ice crystals which form at very high altitudes in the atmosphere. A few may indicate fair weather. They are sometimes called, “mare’s tails”.

• air mass

• atmosphere

• cirrus

• cold front

• warm front

Forms when a one large group of air bumps into another large group of air that is not moving or is moving at a slow pace. As it passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning. Temperaures decrease after it moves through.

Forms when a one large group of air bumps into another large group of air that is not moving or is moving at a slow pace. It often brings rain. Temperatures increase after it moves through.

NGSS.MS-ESS2-6

Forms when two different front stop moving. This happens when large groups of air are pushing against each other, but neither is powerful enough to move the other. Weather is often cloudy.

• stationary front

• Coriolis effect

• low pressure

• high pressure

NGSS.MS-ESS2-6

It is caused by the Earth rotating. It makes currents of air and planes that are traveling long distances appear to move in a curve. This is why hurricanes twirl in a circular motion. It helps scientists to predict wind patterns and it affects ocean currents.

• Coriolis effect

• low pressure

• high pressure

NGSS.MS-ESS2-6

A pressure system that has less air pressure in its center than the areas around it. This can cause unsettled weather like rain or storms.

• stationary front

• Coriolis effect

• low pressure

• high pressure

NGSS.MS-ESS2-6

A pressure system that has more air pressure in its center than the areas around it. The weather is usually fair and drier in this system. This can cause warm and nice weather in the summer and different effects in the winter.

• stationary front

• Coriolis effect

• low pressure

• high pressure
