Cloud
Consist of billions of tiny water droplets (and even ice crystals) and clouds form when raising air cools and the moisture in it condenses to water droplets.
Nimbus clouds
Are rain bearing clouds that are dark and ragged at the edges.
Cumulus clouds
Are fluffy like pieces of cotton. Often they are thick and extend very high in the sky.
Stratus clouds
Are flat layers that form close to the Earth. They are often connected with stormy weather.
Cirrus clouds
Are thin wispy and form high in the sky. They appear before a change in the weather.
Water cycle
The process in which water moves through the ground, evaporates from the earth into the air, forms clouds, and falls back to earth.
Precipitation
Rain, snow, sleet, or hail.
Condensation
The process in the water cycle by which gas becomes a liquid.
Evaporation
The process in the water cycle in which a liquid becomes a gas because water was heated.
Runoff
Water flowing over the Earth's surfaces into the lakes, rivers, and oceans.
Groundwater
Water that has soaked into the soil.
Weather
The state of atmosphere at a certain time and place.
Temperature
Is the measure of how warm or cold something is.
Climate
is the average weather conditions in an area over a long period of time.
Rotation
Earth spinning around once every 24 hours, resulting in day and night.
Revolution
Is Earth moving in a path around the Sun, resulting in one Earth year.
Humidity
the amount of water vapor in the air.
Latitude
The distance from the equator can determine weather and climate, closer to the equator, the warmer the temperature.
Barometer
Measure air pressure
Rain gauge
Measure the precipitation
Meteorologist
A person who forecasts the weather and studies the climate patterns.
Wind
Is caused by differences in air pressure
Air mass
A large body of air that has the same temperature and level of humidity thoughout.
Cool air masses
Where the land temperature is cool.
Low pressure system
Hotter temperature and more moisture, brings warm, wet weather
High pressure system
Cooler temperature and less moisture, brings cold, dry weather
Occluded front
Forms when a warm air mass is caught between two cold air masses.
Stationary front
Occurs when a warm air mass and a cold air mass meet.
Cold front
A cold air mass moves under a warm mass & pushes the warm air upward.
Warm Front
Forms when warm air bumps with colder air.
Anemometer
A gauge for recording the speed and direction for wind.
Altitude
The farther up you go the temperature decreases. Air is less dense and cannot hold the heat.
Sea Breeze
The movement of air caused by cool air over the ocean moving toward the land.
Land breeze:
The movement of air created by cool air over land moving toward the ocean.
Mountain breeze
The movement of air caused by cool air sinking and moving down the slope of a mountain.
Valley breeze
The movement of air created by warm air rising and flowing up the slope of a mountain.
Mountains and Weather
Temperature in mountainous areas tend to be lower than those in a flat area.
Hygrometer
a tool for measuring humidity, or how much moisture is in the air
Wind/weather vane
a tool for measuring wind direction
thunderstorm
rain, thunder, lightning
hurricane
a storm with a violent wind over or near the ocean
tornado
a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.
thermometer
a tool that measures heat or temperature
Fog
a cloud on the ground
jet stream
a fast moving ribbon of air that moves from west to east in the Northern Hemisphere
prevailing westerlies
winds that move from west to east in the temperate regions of earth
trade winds
winds that move from east to west in the tropical region
polar easterlies
winds that blow from east to west in the polar region
El Nino
unusually warm water in the Pacific Ocean, causes unpredictable, destructive weather around the world
La Nina
unusually cold water in the Pacific ocean that affects weather around the world
Transpiration
the process of plants absorbing water through their roots, then releasing water into the air through their leaves as water vapor
precipitation
water falling from clouds as rain, sleet, snow, or hail
