2. Weather Systems, Climatic Change, Microclimates
Question | Answer |
---|---|
parcels of air rising through the environment have relationships with the surrounding air that causes them to | continue to rise or sink beyond the initial triggers |
the presence of continents and oceans strongly influences | weather phenomena at a smaller scale than the planetary systems |
at a smaller scale, human activities such as the creation of large settlements and cultivated lands, have influenced | atmospheric conditions in specific areas (microclimates) |
human activity has significantly influenced the earth's | atmospheric conditions. it is accelerating natural climate change by varying the composition of the air |
carbon pollution is resulting in | global warming with potentially disastrous consequences such as rising sea level and unpredictable weather. the results of accelerated global warming are becoming more and more apparent |
atmospheric pressure falls with | height and the parcel expands losing heat |
adiabatic cooling | the process by which the temperature of an air mass decreases as the air mass rises and expands |
there are 2 different adiabatic lapse rates depending on | the relative humidity of the rising parcel of air |
the 2 different adiabatic lapse rates | -dry adiabatic lapse rate (DALR) -saturated adiabatic lapse rate (SALS) |
dry adiabatic lapse rate | ?? |
saturated adiabatic lapse rate | ?? |
