Today we will certainly take Monday’s post on temperature inversions a step additional with a discussion on atmospheric stability and the species of weather we have the right to expect with a stable and unstable wait mass.

You are watching: What are characteristics of a moist, unstable air mass?

Atmospheric stability is characterized as the resistance of the environment to upright motion. A stable setting resists an increase or downward movement. An turbulent atmosphere allows an upward or downward disturbance to thrive into a upright (convective) current.

Determining the stability of the environment requires measure the difference in between the really existing (ambient) temperature lapse price of a provided parcel that air and also the dried adiabatic price (a continuous 3°C every 1,000 feet lapse rate).

A stable layer that air would certainly be associated with a temperature inversion. Warming from below, top top the other hand, would decrease the security of an wait mass.

The conditions and characteristic of stable or rough air masses are shown in the number below.

Like most things in life their space benefits and drawbacks to both atmospheric conditions. If the visibility might be great in an turbulent air mass girlfriend are most likely to encounter rough conditions and possibly wind shear. In a secure air mass because the air is stagnant (or lack of upright motion) friend will have actually a lot smoother ride however visibility might be decreased due to hazy conditions.

Take a look at few of these sample FAA knowledge test questions and also see if you have the right to answer them. The AC 00-6B is a good additional reference to aid with your knowledge on atmospheric stability.

1. What kind weather can one expect from moist, turbulent air, and an extremely warm surface ar temperatures?A—Fog and also low stratus clouds.B—Continuous hefty precipitation.C—Strong updrafts and also cumulonimbus clouds.

2. What are the attributes of secure air?A—Good visibility; stable precipitation; stratus clouds.B—Poor visibility; secure precipitation; stratus clouds.C—Poor visibility; intermittent precipitation; cumulus clouds.

3. A moist, unstable air mass is defined byA—poor visibility and also smooth air.B—cumuliform clouds and showery precipitation.C—stratiform clouds and continuous precipitation.

4. I beg your pardon is a characteristic usual of a stable air mass?A—Cumuliform clouds.B—Showery precipitation.C—Continuous precipitation.
