Modeling of moist-adiabatic temperature?

In summary, The conversation discusses the need to find articles or books related to modeling the process of a parcel of air rising from the surface to the top of the troposphere, taking into account various conditions and factors such as temperature, pressure, humidity, and the latent heat of condensation and freezing. Some suggested keywords for this topic include orographic rain, adiabatic lapse rate, katabatic, and meteorological handbook. The conversation also raises questions about the possibility of developing equations for this problem and the potential variations in the conditions.

Hi,

I need to find some good article or book related to the modeling of this process:

the parcel of air goes up from the surface to the top of troposphere ( to 12000 m ),
we know the conditions at the bottom such as temperature, pressure and humidity,
we assume that
the parcel is isolated from the surrounding air so it is the moist-adiabatic process,
part of the condensed water can rain down from the parcel ( need some estimate ),
it is necessary to model the temperature of this parcel with taking into account the
latent heat of condensation and freezing.

It would be nice to find even some good keywords for this.

Orographic rain, adiabatic lapse rate, katabatic, should get you started far as keywords. General reading? Grab a meteorological handbook.

This sounds suspiciously like a homework problem in sheep's clothing. Is it a homework problem?

Have you considered developing the equations for this problem yourself?
Could you do it if the air was bone dry?
Could you do it if the water was present but did not condense?
Could you do it if the condensed water were not removed?

Related to Modeling of moist-adiabatic temperature?

1. What is moist-adiabatic temperature?

Moist-adiabatic temperature is the temperature that a parcel of air would have if it were lifted adiabatically (without exchanging heat with its surroundings) to a higher altitude, while being saturated with water vapor. It is also known as the "wet-bulb temperature."

2. How is moist-adiabatic temperature calculated?

Moist-adiabatic temperature is calculated using the dry adiabatic lapse rate and the saturation vapor pressure of water. The calculation takes into account the decrease in temperature as air rises due to expansion, as well as the release of latent heat when water vapor condenses to form clouds. It can be calculated using mathematical equations or by using a chart or graph.

3. Why is modeling of moist-adiabatic temperature important?

Modeling of moist-adiabatic temperature is important because it allows us to understand and predict changes in atmospheric conditions, such as the formation of clouds and precipitation. It is also crucial for meteorologists and climatologists to accurately model moist-adiabatic temperature in order to make weather forecasts and study climate patterns.

4. How does moist-adiabatic temperature affect weather patterns?

Moist-adiabatic temperature plays a significant role in weather patterns. As air rises and cools, it reaches its dew point and water vapor condenses to form clouds. This process can lead to the development of precipitation, such as rain or snow. The temperature of the air also affects the type of precipitation that falls, with colder temperatures leading to snow and warmer temperatures leading to rain.

5. Can moist-adiabatic temperature be affected by human activity?

Yes, human activity can affect moist-adiabatic temperature through the release of greenhouse gases, such as carbon dioxide, into the atmosphere. These gases trap heat and can lead to an overall increase in temperature, including the moist-adiabatic temperature. This can have significant impacts on weather patterns and climate change.
