Sent: Latent heat has a solid, liquid, and gas.

 

Ex: Change and melting

Term

 

Saturation Point

[image]

Definition

Def: Stage where no more of a substance can be absorbed into a type of solution

 

Sent: In the saturation point, nothing can be accepted.

 

Ex: sponge absorbed and dew point

Term

 

Relative humidity

[image]

Definition

Def: Percentage of water vapor in the air shown as amount needed for saturation in the same temperature.

 

Sent: Relative humidity (RH) is a ratio

 

Ex: 100% in 10 degrees, 28% in 30 degrees

 

Term

 

Hygrometer (sling psychrometer)

[image]

Definition

Def: Instrument used to measure moisture in the atmosphere

 

Sent: The hygrometer was first invented in 1755 by Johann Lambert

 

Ex: psychrometer, thermometers

 

Term

 

Dew Point

[image]

Definition

Def: Temperature which air must be cooled to reach saturation

 

Sent: Dew point measures the moisture in the atmosphere

 

Ex: dew on grass, flowers

Term

 

Adiabatic Rates

[image]

Definition

Def: rate of temperature occuring when there is rising or decreasing air parcel takes place.

 

Sent: Adiabatic rates are also lapse rates

 

Ex: pressure, density

Term

Clouds

  [image]

Definition

Def: Mass of condensed water vapor that floats in the atmosphere

 

Sent: Clouds form by rising and cooling of air and water vapor

 

Ex: Cirrus and Cumulus

Term

 

Air mass

[image]

Definition

Def: Volume of air based on its temperature and water vapor

Sent: Air masses usually cover many miles

Ex: northern, tropical

Term

 

Air pressure

[image]

Definition

Def: pressure exerted by weight of air on Earth

 

Sent: Gravity is involved with air pressure on Earth

 

Ex: Balloons, water

Term

 

Barometer

[image]

Definition

Def: Instrument measuring atmosphere pressure

 

Sent: Barometers determine height above sea level

 

Ex: mercury, mechanical

Term

 

Wind

[image]

Definition

Def: Natural movement of air in a form of a current blowing from a certain direction

 

Sent: Wind is air blowing in a natural motion.

 

Ex: local, land breeze

Term

 

Isobar Map

[image]

Definition

Def: Lines drawn on a weather map for atmosperic pressure.

 

Sent: Isobars can help show areas of low and high pressure

 

Ex: 1000mb, 1020mb

Term

 

Factors affecting wind

[image]

Definition

Def: Factors that affect wind deal with forces and pressure

 

Sent: Factors that affect wind can be involve friction

 

Ex: pressure gradient force, Coriolis effect

Term

 

Condensation Nuclei

[image]

Definition

Def: small particles of a cloud droplet when it condenses

 

Sent: Cloud Condensation Nuclei can also be known as "Cloud seeds"

 

Ex: dust, salt crystal

Term

 

Cyclones

[image]

Definition

Def: System of winds that rotate inward to areas of low pressure

 

Sent: Some effects of cyclones include heavy rain, strong winds, and tornadoes.

 

Ex: Tropical storm, a depression

Term

 

Anticyclones

[image]

Definition

Def: System where high atmospheric pressure is at the center

 

Sent: Anticyclones circulate clockwise

 

Ex: calm, fine weather

Term

 

Cold Front

[image]

Definition

Def: cooler mass of air replacing a warmer mass of air on ground

 

Sent: Cold fronts usually move from northwest to southeast.

 

Ex: cold & dry

Term

 

Warm front

[image]

Definition

Def: A warm mass of air replacing a colder mass of rain on ground

 

Sent: Warm fronts usually move from southwest to northeast

 

Ex: moist and warm

Term

 

Stationary front

[image]

Definition

Def: A pair of air masses where niether are strong enough to replace each other

 

Sent: When a cold and warm front stops moving, it becomes a stationary front

 

Ex: blue spikes and red domes on line

Term

 

Occluded front

[image]

Definition

Def: When a cold front overtakes a warm front

 

Sent: In a storm, the cold front roates and catches the warm front

 

Ex: less dense and a lot colder

Term

 

More factors affecting wind

[image]

Definition

Def: Coriolis effect, friction, and pressure affect wind direction

 

Sent: Several factors affect wind and wind direction

 

Ex: currents and wind system

Term

 

El Nino

[image]

Definition

Def: Climating changes occuring in the equatorial Pacific reigion

 

Sent: El Nino events occur every few years

 

Ex: warm & poor nutrient water

Term

 

La Nina

[image]

Definition

Def: Associated with cooler temperatures in the equatorial Pacific Ocean

 

Sent: La Nina and El Nino associate with opposite temperatures

 

Ex: drier & sunnier weather

Term

 

Doppler Effects

[image]

Definition

Def: Change in frequency for an observer moving relative to the source

 

Sent: In the Doppler effect, getting closer to the source builds up higher frequency

 

Ex: low & high

Term
