(5 points) 5) why is warm, moister air related to low pressure? (5 points) 6) in a hypothetical city such as gotham city, the temperature is dropping and the skies are clearing. how would the barometer be changing? (4 points) 7) on another day in gotham city, the temperature is rising, the skies are getting cloudy, and some precipitation begins to fall. how would the barometer be changing? (4 points)

6.) The barometer would show a decrease in wind speed resulting in the dissipation of cloud cover because of the lack of wind, and also because the temperature is dropping there is less precipitation because there is no hot air rising to create clouds.

7.) If it is getting cloudy, it is because the air is rising. This is what causes the condensation of the moisture by adiabatic cooling of a lesser pressure aloft. If the air is rising, the pressure must fall. The barometer will show a lesser pressure. The temperature, on the other side, has very little to do with it.

Hai, how you a doin?

1)    What is air pressure? (Answer: Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth.)

2)    What is a barometer and what is it used to measure? ( A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather.)

3)    How does air pressure change?  ( Millibar values used in meteorology range from about 100 to 1050. At sea level, standard air pressure in millibars is 1013.2. Weather maps showing the pressure at the surface are drawn using millibars. ... This change in pressure is caused by changes in air density, and air density is related to temperature.)

4)    Why is cooler, drier air related to High Pressure? ( This is due to density differences between the two air masses. Since stronger high-pressure systems contain cooler or drier air, the air mass is denser and flows towards areas that are warm or moist, which are in the vicinity of low pressure areas in advance of their associated cold fronts.)

5)    Why is warm, moister air related to Low Pressure?  ( When air warms, its molecules scatter. The air becomes lighter and rises.)
