Measure of how hot or cold something is
What is temperature?
Used to measure humidity
What is a Psychrometer?
Measure of transparency of the atmosphere
What is Visibility?
Air rises, and the center rises, cooling the air. Brings Rainy Weather.
25% of the sun's energy is reflected by them, and they help cool and warm Earth
What do clouds do that affect climate?
What is a thermometer?
Any form of water that falls to Earth from the clouds
What is Precipitation?
Stationary and Moving Technology
What are two forms of technology used to gather weather data?
Affects wind speeds and direction. Also affects overall movement of surface air from the poles to the equator.
How do Global Wind Patterns affect Local Weather?
Air cools to the Dew Point, or Water Droplets/Ice Crystals from on Nuclei
How do Clouds form?
The amount of water vapor in the air
What is Humidity?
Rain, Snow, Sleet, and Hail
What are the four main forms of Precipitation?
Large Volume of Air
What is an Air Mass?
They affect temperature and precipitation
What do changes in weather do Jet Streams cause?
50% of solar energy causes evaporation, making clouds
What is the role of solar energy in cloud formation?
Amount of water vapor in the air compared to the amount needed for saturation
What is Relative Humidity?
Force of air molecules pushing on an area
What is Air Pressure?
Boundary between 2 air masses
What is a Front?
Currents move heat from one part of Earth to another
What does the ocean do to influence weather?
Frontal and Orographic Lifting
What processes cool air enough to form clouds?
Temperature when more condensation than evaporation occurs
What is the Dew Point?
Used to measure air pressure
What is a Barometer
Air sinks slowly, and spreads to low pressure area when near ground. Brings Clear Weather
What is a High-Pressure System?
Collection of Water Droplets or Ice Crystals suspended in midair
What are Clouds?
Water vapor that condenses near Earth's Surface
What is Fog?
