- Quick Answer. Air pressure affects the weather by influencing the movement of air around the planet; areas of low pressure generally develop clouds and precipitation, while areas of high pressure tend to bring clear, sunny weather conditions. Air pressure refers to the force exerted by the atmosphere on the surface of the Earth.

Factors Affecting Arctic Weather and Climate Changes in atmospheric pressure can indicate what the weather will be like. A decrease in pressure indicates an approaching low-pressure system, which is associated with cloudy and wetter conditions. An increase in pressure indicates an approaching high-pressure system, which is associated with clear and dry conditions.

Weather - Solar Energy, Humidity, Clouds, And Precipitation, Atmospheric Pressure And Winds, Terrestrial Characteristics conditions air earth meteorology. Weather can be defined as the condition of the atmosphere at any given time and place. Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.

How does air pressure affect weather? Trending Now. Answers. Best Answer: If there is a low pressure over a place, winds converge there leading to convection,condensation and precipitation.If there is a high pressure area,winds diverge from that area due to sinking of air from above leading to warming up of air resulting in dissipation of clouds thereby causing fair weather.

- Air pressure also affects evaporation. If air pressure is high on the surface of a body of water, then the water will not evaporate easily. The pressure pushing down on the water makes it difficult for water to escape into the atmosphere as vapor. Storms are often high-pressure systems that prevent evaporation. Temperature, of course, affects how quickly evaporation happens. Boiling-hot water will evaporate quickly as steam. Evaporation is the opposite of condensation, the process of water vapor turning into liquid water.

7 Types of Weather in a High Pressure System 1 Weather in a high pressure system is usually drier. 2  As the sinking air increases in pressure and temperature, the number of clouds in the sky decreases leaving less chance for precipitation. 3  Some avid fishermen even swear by a rising barometer to get their best catches!ir pressure is typically reported in units called millibars or inches of mercury. 1  The origin of a high pressure zone will determine the type of weather to come. 2  If a high pressure zone moves in from the south, the weather is usually warm and clear in the summer.

EFFECT OF Air PRESSURE ON WEIGHT When ambient air pressure is higher (for a given temperature), the density of the air will be higher, so buoyancy will be increased - just slightly. There is pressure above you pushing down and trying to increase your weight, but there is just as much pressure below you pushing up trying to decrease your weight. So they ALMOST balance out. But, there's actually slightly more air pressure below you than above you, so the overall total effect is that your weight actually gets decreased. This is the upward thrust you speak of, otherwise known as buoyancy. It takes the pressure above you into account. Thanks , for appropriate explanation.

Higher temperatures affect intensive rain showers The volume of rain that falls in a heavy shower depends on the amount of water vapour in the atmosphere. At higher temperatures the atmosphere may contain more water vapour, thus increasing the chance of heavy showers.eavy rain showers, such as summer thunderstorms, are influenced more by temperature than rain from larger widespread rain systems. Heavy rain has far-reaching consequences for society, and these could worsen at higher temperatures. “Imagine a summer thunderstorm with sudden intensive rain showers over a short period.

How does rain conditions affect barometric pressure? Confidence votes 1.1K. Actually it's the other way around because decreasing barometric pressure initiates the upward flow of air that is essential for cloud development and then rain. Hope this helps! :) Actually no, because decreasing barometric pressure at the surface is a result of rising air and it also causes convergence of air at the surface.

How to Read a Barometer Teaching Procedures. When the air is dry, cool, and pleasant, the mercury or barometer reading rises. When the air is warm and wet, the barometer reading falls. When the air pressure falls, it usually indicates some type of storm or wet weather is coming. When it rises, it often means clear weather.If the barometer remains steady, there will be no immediate change in the weather. rising barometer indicates increasing air pressure; a falling barometer indicates decreasing air pressure. Years ago the French scientist and philosopher Blaise Pascal, discovered that air pressure decreases with height, and pressure changes at ground level at any one place can be related to daily weather changes.

How does wind affect air pressure? Atmospheric pressure changes because where the sun heats the earth, the warm air rises and that reduced the pressure. Where cold air sinks, it increases the pressure. The wind is simply the air trying to balance the pressure between those two systems.tmospheric pressure changes because where the sun heats the earth, the warm air rises and that reduced the pressure.

What does it mean when a barometer is rising or falling? These same sort of pressure differences occur all over the planet for various reasons. These pressure differences have a big effect on the weather, so if you know the current air pressure at your house, as well as the pressure trend, you are able to predict certain things about the weather. As a very loose rule, a high-pressure area will be clear, and a low-pressure area will be cloudy and rainy.
