The Atmosphere Around You
Atmosphere
1 of the 3 ways water is released into the atmosphere.
1. evaporation
2. transpiration (plants)
3. respiration (living animals)
Name one of the four air masses over the United States.
Maritime Polar
Maritime Tropical
Continental Polar
Continental Tropical
Name one of the four types of weather technology.
1. weather balloons
2. weather satellites
3. automated weather station
4. computer forecasts
What is a violent disturbance in the atmosphere that involve sudden changes in air pressure, which cause rapid air movement and often precipitation?
Storm
This gas makes up 78% of the atmosphere.
Nitrogen
The temperature at which condensation begins.
Dew Point
a warm air mass gets caught between two cold air masses, the warm air mass is prevented from reaching the ground
Occluded Front
What is the name of the warm ocean current that influences temperature on the east coast of North America?
The Gulf Stream
What are the four main types of severe storms?
1. Winter Storms
2. Thunderstorms
3. Hurricanes
4. Tornadoes
Air moving from areas of higher pressure to lower pressure creates this.
Wind
What does a sling psychrometer measure?
Relative Humidity
What is an area of low pressure with winds spiraling into the center, counterclockwise.
Cyclone
What connects areas with the same temperature on a weather map?
Isotherms
Name the type of storm: this took place in June, there was heavy precipitation, frequent thunder, and dangerous lightning
Thunderstorm
Altitudes affect on air pressure.
As altitude increases, air pressure decreases.
Name the sizes of water drops from smallest to largest (4):
Smallest: droplet
mist
drizzle
Largest: rain
Name the front: When a cold air mass runs into a warm air mass. Can result in abrupt and hazardous weather: heavy rain, winds, thunderstorms, tornadoes
Cold Front
What's the name of a scientist who studies and predicts weather?
Meteorologist
What year was the Fujita Scale developed and then enhanced?
1971 and 2007
This is the uppermost layer of the atmosphere, with the lowest density of air. Temps can reach up to 1800 degrees Celsius, but it can feel extremely cold.
Thermosphere
Water is continually evaporating and condensing in the atmosphere forming clouds. Once the droplets grow heavy enough gravity pulls it down to earth. What is this process?
The formation of rain and precipitation
Name the front: cold and warm air masses meet, but neither one can move the other, can form rain, snow, fog, or clouds
Stationary Front
What are lines that connect areas with the same air pressure?
Isobars
There are two levels of potentially dangerous storm announcements. Name those two.
