Yes.
increasing
A pressure switch tagged PSL 1234 is typically set to trip on increasing pressure if it is designed to activate when the pressure exceeds a certain threshold. Conversely, if it is intended to activate when the pressure drops below a specified level, it would trip on decreasing pressure. The specific function would depend on the application and configuration of the switch. Always refer to the manufacturer's documentation for the exact operation of a particular pressure switch.
Pressure drops when the temperature drops.
Before a tornado, air pressure drops significantly. This drop in pressure is due to the strong updrafts within the thunderstorm that eventually leads to tornado formation. The rapidly decreasing pressure can be one of the early indicators of an impending tornado.
When air pressure drops temperature also drops. Thus on high mountains low air pressure is accompanied by low temperature. This is true for high atmosphere also.
If the air pressure drops largely, there will be rain and/or a thunderstorm. If the air pressure drops not so much, it will be partly cloudy and/or breezy. If the air pressure barely drops, and stays more of a high air pressure, it will be sunny and calm. If the air pressure is about in the middle of the Anemometer, it will be partly cloudy. Also, I did not use this from any other website, this answer is from common sense (for me). Have a good day! =)
In most storms, which always includes hail storms, the barometric pressure drops. Which the pressure drops, that would allow clouds to form. The more it drops, the more intense the storm can get.
Pressure drops as you go up.
Blood pressure would decrease
The air pressure drops sharply in a tornado
Because as atmospheric pressure drops with altitude, the total oxygen available to the engine drops. The fuel injection maintains the mixture by decreasing the fuel flow. Rule of thumb - at 8500' MSL, a normally-aspirated engine will produce about 50% of the power it produces at sea level.
Adiabatic cooling is cooling as a result of reduced air pressure(i.e. rising air)
