What is the difference between the normal lapse rate and the environmental lapse rate?
The environmental lapse rate (ELR), is the rate of decrease of temperature with altitude in the stationary atmosphere at a given time and location.While Normal Lapse Rate is average concept for temperature decline with height in the troposphere.
1 degree c of cooling per 160 meters of altitude?
occurs in the tropopause- environmental lapse rate or normal elapse rate ELR
Stability prevails when the environmental lapse rate is?
Stability prevails when the environmental lapse rate is less than the adiabatic lapse rate. This means that the temperature of the surrounding air decreases at a slower rate with altitude compared to the dry or moist adiabatic lapse rates, resulting in a more stable atmosphere.
What environmental lapse rate does stability prevail?
less than the wet adiabotic rate
What is normal lapse rate?
6.5 degrees Celsius/1000 m
What is the actual decrease in temperature with an increase in altitude through the tropospher?
Environmental lapse rate
Why is saturated adiabatic lapse rate a lesser than dry adiabatic lapse rate?
The saturated adiabatic lapse rate is lower than the dry adiabatic lapse rate because during the process of condensation, heat is released into the atmosphere, which partially offsets the cooling effect of rising air. This release of heat makes the cooling rate of saturated air less than that of dry air as it ascends through the atmosphere.
When the environmental lapse rate is between the dry and moist adiabatic lapse rates conditions are described as what?
When the environmental lapse rate is between the dry and moist adiabatic lapse rates, conditions are described as conditionally unstable. This means that the atmosphere is stable when unsaturated and unstable when saturated, indicating the potential for convective storms to develop under the right conditions.
What must the environmental lapse be in order for stability to prevail?
less than the wet adiabatic rate.
The rising and subsequent cooling of air at the rate of 10C per 1000 meters is called?
This process is known as the environmental lapse rate, which describes how air temperature changes with altitude in the Earth's atmosphere. A decrease of 1 degree Celsius per 100 meters in altitude is a standard approximation for the environmental lapse rate.
Assuming a normal environmental lapse rate of 6.5 C per 100 meters and a surface temperature of 30 C at what elevation would a temperature of 4 C be found?
400 meters
When the environmental lapse rate is less than the dry adiabatic rate a parcel of air will be?
Then the air is called "stable" because a parcel of air from the surface lifted upward will drop in temperature at the dry adiabatic lapse rate. If the environmental lapse rate is less, then the lifted air will be cooler and more dense than the surrounding air, and thus stop moving upward through the atmosphere.
