thats what i was looking for and i knoe the answer but im not giving it to you
It Helps Warth Ritete
idk lololol
Air Pressure
It expands, rises, and becomes less dense.
A barometer measures air pressure.
Depending on the air pressure the weather system can be hot of cold
The Barometric Trend will tell you the air pressure. If the air pressure is high the weather will be clear and sunny, but if the air pressure is low the weather will be cloudy.
Air movement plays a key role in the formation of weather in high and low pressure systems. In high pressure systems, air sinks and moves outward, leading to clear skies and generally fair weather. In low pressure systems, air rises and ascends, causing moisture to condense and cloud formation. This typically results in unsettled weather conditions such as clouds, precipitation, and storms.
Air pressure does make quite a difference in weather. In this question, we are talking about high pressure areas and low pressure areas. In High Pressure areas, this doesn't allow for cloud formation, so we end up getting very nice weather. Low Pressure areas are the exact opposite, this allows for cloud formation, so we end up getting rainy weather. High Pressure Areas are represented with a blue H on a weather map. Low Pressure Areas are represented with a red L on a weather map.

Air Pressure
Yes, because meteorologists use a barometer which measures atmospheric air pressure and a barometer is a weather instrument so air pressure is part of the weather
The atmospheric pressure plays a huge role when determining the weather. If the pressure is high, winds will be more active.
Usually rising air pressure means that the weather will improve.
With all low pressure systems, they allow for cloud formation. Which means you would get a cloudy/rainy day.
It expands, rises, and becomes less dense.
Air pressure relates to weather conditions, and weather was very important to farmers.
yes the air pressure changes
In general High Pressure promotes atmospheric stablity (clear sunny weather) and warmer temperatures, while Low Pressure promotes atmospheric instablity (storminess) and somewhat cooler temperatures. In low pressure systems in the northern hemisphere air rotates in a counterclockwise direction and moves upward. This promotes cloud formation cooler temps and sometimes storms. In high pressure systems in the northern hemisphere air rotates in a clockwise direction and moves downward (subsidence). This inhibits cloud formation and usually increases temperatures.
