It has a significant negative impact on aircraft safety.

Weather hazards.

Airport Terminal Area: Local Airport Weather

All of the above

En-Route: Regional and Global scales Weather

Thunderstorms (hail, turbulence), Clear Air Turbulence (CAT), & Icing (regional flights at lower altitudes)

What are the five atmosphere layers?

exosphere, thermosphere, mesosphere, stratosphere, & troposhere.

It is the layer closest to Earth's surface and is 4 to 12 miles (7 to 20km) thick and contains half of Earth's atmosphere.

troposphere.

Nearly all of the water vapor and dust in the atmosphere are in this layer and that is why clouds are found here.

troposphere.

It extends from about 56 miles (90km) to between 310 and 620 miles (500 and 1,000km).

thermosphere.

Temperatures in this layer can get up to 2,700°F (1,500°C).

thermosphere.

This is where the space shuttles flew and where the International Space Station orbits Earth. This is also the layer where the auroras occur.

thermosphere.

This is the highest layer and is extremely thin and is where the atmosphere merges into outerspace.

exosphere.

This layer is composed of very widely dispersed particles of hydrogen and helium.

exosphere.

There is no distinct boundary between the atmosphere and space, but an imaginary line about 62 miles (100km) from the surface called __________ and is usually where scientists say atmosphere meets outer space.

Karman line.

Line between stratosphere and troposphere called ______

Ozone layer.

Line between exosphere and thermosphere is called _______

Exo base

Layer where passenger planes fly

stratosphere.

According to the World Meteorological Organization's International Cloud Atlas, more than how many types of clouds exist?

100

Low-level clouds that lie below 6,500 feet (1,981 m)

cumulus, stratus, stratocumulus.

Middle-clouds that form between 6,500 and 20,000 feet (1,981 - 6,096 m)

altocumulus, nimbostratus, altostratus.

High-level clouds that form from above 20,000 feet (6,096 m)

cirrus, cirrocumulus, cirrostratus.

Which cloud tower across the low, middle, and upper atmosphere?

cumulonimbus.

The rate which saturated air cools with height and is, at low levels and latitudes, 1.5°C per thousand feet.

Saturated Adiabatic Lapse Rate (SALR).

This lapse rate is not constant because the air does not have a uniform temperature. It means that the air has different densities at different heights and will expand or contract depending on its density.

Saturated Adiabatic Lapse Rate (SALR).

What is the reason why air has different densities at different heights and will expand or contract depending on its density? Because of ...

convection.

Why is the moist adiabatic lapse rate different from dry adiabatic lapse rate?

The moist adiabatic lapse rate of cooling is less than the dry adiabatic lapse rate of cooling because moist air rising condenses out its water vapor (once saturation is attained). This condensation releases heat which results in a slower rate than if no condensation took place (cooling dry adiabatically).

The lowest layer of clouds reported as being broken or overcast, or vertical visibility into an obstruction like fog or haze.

ceiling.

Cloud layers

Few (1-2 octas), Scattered (3-4 octas), Broken (5-7 octas), Overcast (8 octas)

It is the greatest horizontal distance at which prominent objects can be viewed with the naked eye.

Visibility.

It is any type of water particles that form in the atmosphere and fall to the ground.

Precipitation.

What are the hazards of precipitation?

All of the above.

This is the term for visibility greater or equal to 10km, no cumulonimbus or towering cumulus, co cloud below 5,000 ft or highest minimum sector altitude (MSA)(whichever is the greater) and noo weather significant to aviation.
