Middle School Science Vocabulary

Land Breeze

• Transfer of thermal energy through circular motion caused by heating and cooling of fluids (liquids/gases)

• The movement of air as a result of Earths rotation. (Northern Hemisphere it curves to the right)

• The breeze that blows from the land toward the sea after the sunset. The land cools more quickly than the ocean cooling the air above it. The warmer air above the water continues to rise and the cooler air from over the land replaces it creating a breeze.

• the breeze that blows from the sea toward the land during the day as air rising over the warmer land is replaced by cooler air from above the sea.

Psychrometer

• tool used to measure wind speed

• a tool that measures the amount of atmospheric pressure

• a tool that measures air temperature

  in the air

Humidity

• movement of air from an area of high density and pressure to low density and pressure. Caused by uneven heating of the earth

• Very dense cool dry air. Brings happy weather.

• Low density air. Brings lousy weather

• The amount of water vapor in the air

Hurricane

• Transfer of thermal energy through circular motion caused by heating and cooling of fluids (liquids/gases)

• tropical cyclones that forms in the southern Atlantic along the equator. MUST BE OVER WARM WATER.

• The movement of air as a result of Earths rotation. (Northern Hemisphere it curves to the right)

El Nino

• Abnormally high surface ocean temperatures off the coast of South America. Causes unusual weather patterns across the globe. It can cause the winds to change directions.

• Abnormally Low surface ocean temperatures off the coast of South America. Causes unusual weather patterns across the Globe.

• tropical cyclones that forms in the southern Atlantic along the equator. MUST BE OVER WARM WATER.

• The movement of air as a result of Earths rotation. (Northern Hemisphere it curves to the right)
