Humidity
This measurement describes how much water vapor is in the air compared to how much it can hold
What is relative humidity
This happens when two different air masses meet.
What is a front?
This part of Earth receives the most direct sunlight.
What is the equator?
Wind moves from areas of _____ to areas of lower pressure.
What is high pressure?
These currents move warm water from the equator towards the poles.
what are warm ocean currents?
When air cools but the amount of water vapor stays the same, this value increases.
What is relative humidity?
This type of front often brings brief, heavy rain or storms.
What is a cold front?
This explains why temperatures are colder at the poles than at the equator.
What is the angle of sunlight?
Closely spaced isobars on a weather map indicate this condition.
What is strong or fast wind?
Coastal areas near warm currents usually have this type of climate.
What is milder or warmer climate?
This is most likely to form when warm, moist air cools near the ground.
What is fog?
This type of front usually causes clouds and precipitation that last for a longer time.
What is a warm front?
As elevation increases, both temperature and air pressure usually do this.
What is decrease?
This instrument measures air pressure.
What is a barometer?
Cold dense water usually does this compared to warm water.
What is sink?
When air reaches 100% relative humidity, this process is likely to begin.
What is precipitation?
This type of front forms when warm and cold air masses meet and neither one moves.
What is a stationary front?
Coastal areas often have smaller temperature changes because of this nearby feature.
What is the ocean?
This usually happens to air pressure as altitude increases.
What is air pressure decreases?
This causes ocean currents to form in global circulation patterns.
What are differences in temperature and density?
Warm air usually has this ability compared to cold air when it comes to water vapor.
What is the ability to hold more water vapor?
This type of front forms when a cold front catches up to a warm front.
What is an occluded front?
This factor best explains why mountaintops are colder than nearby lowlands.
What is elevation?
Meteorologists use this data to predict both wind speed and wind direction.
What is air pressure data (or pressure maps)?
These features on a weather map are most helpful for predicting future weather.
What are fronts and pressure systems?
