A worn out, tired, high mileage or abused engine could cause low oil pressure.
Bad compressor valves most likely... If the expansion valve or orifice tube is stuck open it will cause this condition also.
if your talking about like how on the news they say high pressure and low pressure, high pressure= clear skies (most likely warmer) and low pressure= cloudy and rainy weather (most likely colder) ... :)
high pressure most likely

Wind will most likely form between the high pressure and low pressure isobars on a weather map.
dehydration, low blood volume, low blood pressure.
If it is an automatic most likely the second gear clutch is worn out and the line pressure is low to it. If it is a manual most likely the pressure plate and disc are worn out or contaminated with oil from the rear seal of the engine.
There is an ac relay, most likely mounted under the hood. There is also a low pressure switch, that will not turn the compressor on if the Freon is too low. Low Freon is the most common cause,
yes it can cause low tire pressure
Cloudy conditions
