high pressure
a high pressure system
No, it is clear and cool weather
It means higher atmospheric pressure, which is generally caused by cool air.
low pressure. because warm air is less dense. so it's pressure is also low.( less dense because because of the heat( warm air = hot air) the molecules of the air is very active. so the the are not close to each other which means less dense)
Depends on the situation. In most cases, high pressure means little or no precipitation. However, sometimes afternoon heating can cause stray thunderstorms to develop even under high pressure. There's also an "overrunning" factor in which low pressure or a trough in the upper atmosphere can cause warmer air to move on top of a cool high pressure that's at ground level. That can cause precipitation to develop in areas of very high surface air pressure.There are also little or no clouds
a high pressure system
A high pressure system is when the air is moist. The effect is dry and cool.
cool, dry weather

Air doesn't necessarily cool as it moves up, generally hotter air is lighter and so moves upward. However in the atmosphere the pressure gradually decreases with altitude, pressure and temperature are state functions and change according to one another. Generally if the pressure decreases (as it does with altitude) the temperature too, decreases.
Cool air is an area of low pressure because temperature is directly proportional to pressure. So when the pressure is low, the air is cool (low temperature).
pressure decreses
Let the engine cool off after being run.The cooling system pressure is a result of the coolant being heated - once the heat dissipates, so will the pressure, making it safe to remove the top of the coolant reservoir.
High pressure is associated with cool, dense air--which can hold LESS wator vapor than warm air. Low pressure would be "moister" than high pressure--meaning it would carry a higher percentage of water vapor or have a higher relative humidity.
You have to wait for it to cool. When it heats up inside a closed system , it builds up pressure .
