D)convergence of the parcel.
E)wind speed.

Question

Quizplus · Accepted Answer

Heat released if water vapor condenses greatly affects the buoyancy of a rising air parcel. As air rises, it cools and can reach its dew point temperature, at which point the moisture in the air can condense into water droplets or ice crystals. This process releases latent heat, which further heats the air parcel, and makes it more buoyant. As a result, the parcel can continue to rise and cool until it reaches an equilibrium level where the temperature of the parcel is the same as the surrounding air. Therefore, the heat released from water vapor condensation is a crucial factor that influences the buoyancy and behavior of rising air parcels.  The other options, such as absorption of solar radiation, air pressure, convergence of the parcel, and wind speed, can also affect the atmospheric conditions, but they may not have a direct impact on the buoyancy of rising air parcels.
