Air Masses, Fronts, and Mid-latitude Cyclones
The name given to a large body of air with similar properties
Air mass
The Enhanced Fujita Scale rates tornadoes based on this factor
Name the 3 types of heat transfer
Conduction, convection and radiation
Air that cannot hold any more water vapor at its temperature and pressure is given this name.
Saturated
The sun is directly over the equator on these days
Equinoxes
The boundary between continental tropical and maritime tropical air masses
Dryline
This is the hurricane hazard responsible for causing the most damage
Storm surge
This is the heat energy required or released during a phase change of a substance
The name given to clouds that extend from low to high altitudes, and are most associated with thunderstorms
Cumulonimbus
The percentages of nitrogen and oxygen in the atmosphere
Nitrogen ~78% Oxygen ~21%
Name the 4 types of fronts
Warm, cold, stationary and occluded fronts
This month sees the highest frequency of hurricanes during the Atlantic hurricane season.
September
This radiation interaction occurs when energy is captured by an object
Absorption
The height of clouds that are better at reflecting solar radiation and cooling the earth
low clouds
This fog occurs on calm, clear nights when moist air near the surface is cooled via contact with the ground
Radiation fog
The number of air masses in the typical mid-latitude cyclone
3
Name one of the 5 enviromnental conditions required for hurricane development
SST >= 80F
Little to no wind shear
Sufficient low level moisture
Warm water depth ~200ft
At least 5 degrees north/south of equator
This is the temperature above which any object will emit some form of radiation
0 Kelvin (Absolute zero)
This process injects IN into clouds, promoting ice crystal growth and enhancing rainfall
Cloud seeding
This is the number of degrees during days where the mean daily temperature is at least one degree below 65F
Heating degree-days
The process of mid-latitude cyclone development is given this name
Cyclogenesis
This scale rates hurricanes by wind speed
Saffir-Simpson scale
This phase of matter can be described as well seperated molecules with no arrangement that move and vibrate freely at high speeds
Gas
This temperature indicates the air temperature required for saturation to occur as well as the relative amount of water vapor in the atmosphere
Dew point temperature
This instrument directly measures rainfall in 0.01 inch increments without storing all the water it collects
Tipping bucket rain gauge
