As the cold front passes, there is a sudden drop in the temperature from 73 F to 45 F.

As the cold front passes, there is a sudden drop in the temperature from 73 F to 45 F. The temperature as well as dew point continued to register a sharp drop. Consequentially, there was a sharp increase in atmospheric pressure. The wind direction shifted from South/Southwest to North/Northwest and was gusty. The sky condition was mostly cloudy with poor visibility.

2) There is a divergence in the conclusions from the single-celled model and actual surface pressure over Antarctica. This divergence is due to the crude assumptions of the single-celled model where the assumptions are too vague to be true. Single-celled model assumptions include water-covered earth with no land. hence the pressure cells development due to the differential heating of land and sea surfaces would not happen. However, in practice, it occurs and is the main driving force behind the formation of a differential pressure system on land and water.
