Question

consider temperature soundings - ground lever, 21C;500m, 20C; 600m, 19C;1000m. If an air parcel is released at 600m does it remain at 600, rise or sink?

Answer 1

According to the principle of atmospheric stability and lapse rate if a warm layer occurs above the air parcel then the parcel will rise due to the buyount lifting as the density of gas changes however when the air parcel was entered at 600 m the temperature of the layer above I. E at 1000m was 19c as compared to 20c at 600m so it will not rise

Now since the temperature of the bottom layer is more than that at 600 m so the gas will be less dense and so the air parcel will settle
