EAPS 106 Exam 4
How climate change can influence the weather. - ✔ ✔ The number of hot and
extremely hot days has jumped dramatically compared to pre-1980 already. Hot
day: temps more than 10 F above seasonal average, extremely hot day: Temps
more than 20 F above seasonal average
More severe and frequent local storms, more extreme temperatures, more
frequent extreme weather events, just take the weather dial and turn it up to
1000
How greenhouse gases cause warming of the Earth's atmosphere. - ✔ ✔
Aerosols are particles in the atmosphere that block sunlight and thus cause
cooling
Albedo is the amount of sun the earth reflects (might be wrong he went too fast)
Greenhouse effect works by converted short-wavelength visible light to longer
wavelength heat and trapping it. Visible light from the Sun passes through the
gasses, the shortwave radiation hits a surface and is converted to heat which is
reemmitted as long wave radiation (infrared), and then the gasses trap most of
the longwave radiation.
The main way we measure the wind speeds, pressure, and temperatures of
hurricanes. - ✔ ✔ We use dropsondes which are instruments dropped from an
aircraft into a hurricane to measure wind speed, directions, humidity,
temperature, and atmospheric pressure.
The major components of the 1991 Perfect Storm. - ✔ ✔ The Halloween Gale
of 1991: The Perfect Storm, was a combination of a cold front, a hurricane, and a
nor'easter (referred to in this clip as a "low off of Sable Island").
The major components of what makes the midwest so productive for tornadoes. -
✔ ✔ Cold dry air from the north collides with warm moist air from the Gulf to
form cumulonimbus clouds.
, Winds from the jet stream cause the cumulonimbus clouds to experience
horizontal shear
Warm dry air from the southwest lifts and rotates the vortices into a vertical
orientation, generating a supercell.
The most difficult task that a rescue swimmer has to deal with. - ✔ ✔ Dealing
with noncompliant people who need rescuing.
The relationship between hurricane category rating and the size of a hurricane. -
✔ ✔ The higher the category storm does not necessarily mean a larger storm
so there is no relationship between the two.
The relative wind and pressure conditions (e.g., high or low) found in the eye and
eyewall of a hurricane. - ✔ ✔ Minimum pressure is reached at the center of
the eye. This low pressure draws in air from the surrounding regions, causing high
winds. The highest winds occur within the eyewall, as winds cannot penetrate
into the eye.
Eye: 960mb (low), 20 km/hr (low)
Eyewall: 1000mb (high), 250 km/hr (high)
The role that mesocyclones play in a supercell. - ✔ ✔ Tornadoes from by
focusing the rotation of supercells into a series of faster rotating structures:
Mesocyclone to wall cloud to tornado. The rapid spinning of a mesocyclone
enables more efficient updraft of warm, moist air, providing more energy for the
supercell resulting in stronger winds.
The similarities and differences between hurricanes and nor'easters. - ✔ ✔
Nor'easters differ from hurricanes in several ways:
Source of energy: While both rely on warm waters, nor'easters require a cold
front (cold core) that lifts the warm moist air
Locations: Nor'easters form in the north Atlantic; hurricanes form in the tropics.•
Snow:Only nor'easters bring snow
