Can someone please help me with these questions??
1. Once a parcel exits the trough, its spin ___________ and its horizontal cross-sectional area __________." In both blanks, choose from: increases / decreases / remains the same.
2. name the process that the parcel undergoes as it exits the trough
3.Once a surface low pressure is formed, what process occurs near the surface as atmosphere tries to compensate for the column weight change cited in part vi (a). Taken by itself, would this process be beneficial or detrimental to the fledgling low pressure system?
4.What classic feature associated with mid-latitude cyclones is causing the heavy precipitation?
5. WHY the 500-mb heights should decrease due to cold air advection. Hint: You must address the rate that pressure decreases with increasing altitude as a function of temperature in your explanation.
Explanation / Answer
ANSWER :
Once a parcel exits the trough, its spin _Decreases__________ and its horizontal cross-sectional area __Increases________."
Explanation : When air parcels exit the trough , they lose their spin ( therefore spin gradually decrease ) resulting in a decrease of vertical height ( therefore increase horizontal cross –sectional area )
2. name the process that the parcel undergoes as it exits the trough
ANSWER :
Name of the process is Adiabatic Process
3. Once a surface low pressure is formed, what process occurs near the surface as atmosphere tries to compensate for the column weight change cited in part vi (a). Taken by itself, would this process be beneficial or detrimental to the fledgling low pressure
ANSWER :
Once the surface low pressure formed then Thermal lows occurs nearthe surface as atmosphere tries to compensate for the column weight changes .
Low pressure can be enhanced by the air column over it being warmed by condensation of water vapor in large rain or snow system .
4.What classic feature associated with mid-latitude cyclones is causing the heavy precipitation?
ANSWER :
classic feature associated with mid-latitude cyclones as follow
the tail of the comma is consists of a line of clouds that typically produce showers and thunderstorm and the head of the comma is produced by cloud s circling the low pressure and consist of clouds that can produce rain ,ice pellets freezing and snow .
