Midterm Questions

what are the base units of SI?

m, s, mole, A, K, cd, kg

What is responsible for increasing air temperature of the troposphere?

sensible heat transfer

what is sensible heat transfer? the energy required to change the temp of a substance with no phase change

the energy required to change the temp of a substance with no phase change

If you have air contained in a sealed bottle that cannot be stretched or compressed and you decrease the temp, what is the effect on \****pressure******?**

pressure decreases

if you have air contained in a sealed bottle that cannot be stretched or compressed and you decrease the temp, what is the effect on ******density*?***

density does not change

what available substance would take the most heat to cause a 5k increase in temp?

ice at 0C

what happens on the summer solstice?

all regions north of the arctic circle experience 24 hr daylight

When will longwave radiation emitted by the earth be absorbed by the atmosphere most readily?

dew point temp is high

what is a situation favourable for fog development?

surface cooling by radiation in the night/early morning

What situation would cause an absolutely unstable situation?

strong radiative heating at the surface

When will air masses with equal temperatures and equal actual vapour pressures have evaporation occur more rapidly?

on a windy day than on a calm day

when will conditions enhance cloud droplet formation and growth?

air with high CCN/aerosol concentration

why do cloud droplets typically no fall to the ground?

small droplets have a low terminal velocity that is easily overcome by updrafts

what information do upper air atmospheric pressure charts provide?

the elevation of a constant pressure surface?

Relative to winds blowing at 10N latitude, winds blowing at what latitude at the same speed will experience what?

a stronger coriolis force

what is true about geostrophic winds is true?

occur when pressure gradient force and coriolis force is in balance
