A high pressure center of dry air is called an anticyclone
Weather patters that most often form tornadoes include wind shear combined with at least one of the following: Extratropical low pressure systems. Cold fronts (cold air plowing into warm air) Dry lines (dry air plowing into moist air) Tropical cyclones (hurricanes, tropical storms, and tropical depressions).
It varies with air temperature, pressure, humidity, and density, and it's completelydifferent in other substances other than air.For normal conditions in comfortable air near sea-level, I use the figure of 343 meters/second.

The perfect setting for a tornado to occur would be: Upper Level winds are strong, and in a very different direction from those near the ground. A low pressure system pulls air from the Gulf of Mexico northward, creating very hot, humid weather. At the same time it pulls in cool air from the north and dry air from the west, pushing those air masses into the warm moist air mass, forming a cold front and a dry line, causing thunderstorms to spring up. The cold front and dry line intersect, forming a triple point. The storms become strong and begin rotating, and have the potential of producing tornadoes. The storms at the triple point are especially violent, and have the greatest potential for producing tornadoes.
Venus has a very hot greenhouse effect. In fact, it makes Venus the hottest planet in the solar system. The thick carbon dioxide atmosphere holds the heat very effectively, like a runaway greenhouse effect. Surface temperatures on Venus average 900° Fahrenheit, 735° Kelvin or 460° Celsius.

high pressure
A high pressure system is when the air is moist. The effect is dry and cool.

Air pressure is highest when it is cool and dry. It is lowest when it warm and humid. In high pressure, the sky is clear and dry, while in low pressure, the sky is warm and muggy and humid, which is where hurricanes can start.
No, that's high pressure. High pressure has sinking air and fair weather. Low pressure is rising air and usually brings lots of clouds and precipitation.
