You are watching: Which gas is most important for understanding atmospheric processes?

1 heat Up 3/14 i beg your pardon gas is most essential for expertise atmospheric processes? a. Water vaporc. Carbon dioxide b. Oxygend. Ozone What is true about warm, saturated air? a.It consists of less water vapor than cold air. B.It contains more water vapor 보다 cold air. C.It does no contain any water vapor. D.It consists of the exact same amount the water vapor as cold air. If the water-vapor content of air stays constant, lowering air temperature causes a(n) ____. A. Diminish in family member humidity b. Rise in loved one humidity c. Rise in evaporation d. Temperature inversion Answers: 1) a. 2) b. 3) b.

3 Air Compression and ExpansionTemperature transforms that happen even though warmth isn’t included or subtracted are called adiabatic temperature changes When waiting is enabled to expand, that cools, and also when it is compressed, the warms any type of time a volume that air moves upward, it passes through areas of successive reduced pressure dried Adiabatic price – the rate of adiabatic warming or cooling in unsaturated waiting (1ºC/100 m) Wet Adiabatic price – the rate of adiabatic temperature change in saturated air; the is always less 보다 the dried adiabatic rate

4 Cloud formation by Adiabatic Cooling

5 Concept inspect What happens to heat stored in water vapor when it is cooled to its dew point? Latent warmth is released.

6 Orographic Lifting and also Frontal WedgingFour mechanisms that can reason air to increase are orographic lifting, frontal wedging, convergence, and also localized convective lifting Orographic Lifting – hills acting as obstacles to the circulation of air, forcing the air to ascend many of the rainiest locations on planet are situated on windward mountain slopes By the moment the air has reached the leeward next of the mountain, much of that moisture has been shed Front – the boundary between two adjoining air masses having actually contrasting qualities The cooler denser waiting acts as a barrier over i m sorry the warmer, less dense air rises

8 Frontal Wedging

9 Convergence and also Localized Convective LiftingWhenever wait in the lower setting flows together, lifting results, this is referred to as convergence This leads to adiabatic cooling and possibly cloud development On warm summer days, unequal heater of Earth’s surface may cause pockets of air to be warmed much more than the bordering air Consequently, this warmer, less thick packet will relocate upward These rising parcels of warmer waiting are dubbed thermals The process that produces increasing thermals is localized convective lifting When warm parcels rise above the condensation level, clouds kind

11 Localized Convective Lifting

12 Concept check What room thermals?Thermals are rising parcels of wait that room warmer than bordering air.

13 security Stable waiting is any kind of air i beg your pardon resists vertical movement due to thickness differences secure air tends to stay in its initial position, while rough air tends to rise Air stability is identified by measuring the temperature the the setting at assorted heights The rate of adjust of waiting temperature with height is referred to as the environmental lapse rate Temperature turning back – a layer wherein the temperature rises with height; the many stable conditions for wait Clouds linked with the lifting of stormy air space towering and also often create thunderstorms and tornados

18 Concept examine What species of weather can result when steady air rises?Clear weather may occur or light-to-moderate precipitation.

19 Condensation Recall that condensation happens as soon as water vapor in the air alters to a fluid in the type of dew, fog, or clouds For any type of of the develops of condensation come occur, the air must be saturated Generally, there should be a surface for water vapor to condensation on Condensation Nuclei – tiny bits of particulate issue that serve as surface on i beg your pardon water vapor condenses once condensation take away place, the initial development rate that cloud droplets is rapid It diminishes quickly because the overabundance water vapor is soaked up by numerous completing particles This outcomes in the development of a cloud consisting of millions upon numerous tiny water droplets
