The Atmosphere
These are the four layers of the atmosphere
What are the troposphere, stratosphere, mesosphere, and thermosphere?
These are the two basic types of cloud formation.
What are cumulus and stratus?
Air moves in this direction around a low-pressure area in the northern hemisphere.
What is counter clockwise?
The atmosphere is heated from here.
What is below?
If the water region lying below the supercooled region of the cloud is not of great depth, the hailstones do not acquire the hard, transparent covering and arrive at the ground as the type of precipitation seen here.
What are snow pellets?
This is the term given to the band located at the top of the stratosphere.
What is the stratopause?
Cumulus, towering cumulus, and cumulonimbus clouds belong to this category of cloud height.
What are clouds of vertical development?
Fair weather is usually associated with this pressure system.
What is a high-pressure system?
This heating process occurs when horizontal movement of cool air over a warm surface allows the cool air to be heated from below.
What is advection?
The lines shown here join areas of equal pressure.
What are isobars?
These are the properties of the atmosphere
What are mobility, capacity for expansion, and capacity for compression?
Water droplets form on these microscopic particles in the atmosphere, allowing condensation to occur.
What are condensation nuclei?
As air moves from a high-pressure system to a low-pressure system, this force causes it to be deflected to the right in the Northern Hemisphere.
What is coriolis force?.
This process of cooling the atmosphere occurs when air is forced to rise, and it therefore expands and cools.
What is the adiabatic process?
The breeze shown here occurs during the day when the land heats up more rapidly than the water.
What is a sea breeze?
This is the standard atmosphere rate of decrease of temperature with height according to the International Civil Aviation Organization (ICAO).
What is 1.98 degrees Celsius per 1 000 feet?
This lifting agent is caused by the heating of the ground by the sun.
What is convection?
This law states that if you stand with your back to the wind, the low pressure area will be on your left side.
What is Buys Ballot's Law?
As temperature nears this, the air will become more saturated.
What is dewpoint?
The type of cloud shown here forms when air is stable.
What are stratus clouds?
From the standpoint of weather, this is the most important component of the atmosphere.
What is water vapour?
When air rises these two things occur, causing condensation and the formation of clouds.
What are expansion and cooling?
This is the standard mean sea level pressure according to ICAO.
What is 29.92 inches of mercury ("Hg) or 1013.2 hectopascals (hPa)?
Once this reaches 100 percent, any addition of water or decrease in temperature will cause precipitation.
What is relative humidity?
The type of lift shown here occurs when the sloping terrain forces the air upward.
What is orographic lift?
