Atmosphere Flashcards
The troposphere -
contains most of the water vapour of the atmosphere and the temperature generally decreases with height
With increasing altitude in the stratosphere, temperature -
increases
The tropopause is-
a region 8 km to 18 km above the earth’s surface at which a marked change in temperature lapse is apparent
In the international standard atmosphere (ISA), from mean sea level to the tropopause, the decrease of temperature with height is at the rate of approximately-
2 degrees C/1000 ft
n the international standard atmosphere (ISA), the tropopause is found at -
a height of 36090 ft
One of the major differences between the troposphere and the stratosphere is that the stratosphere -
has almost no clouds
From the earth’s surface, the vertical structure of the atmosphere is -
troposphere, tropopause, stratosphere
The lapse rate in the stratosphere is due to -
the presence of heat absorbing ozone
The section of the atmosphere in which most weather occurs is the -
troposphere
The temperature at the base of the stratosphere is lowest over -
the equator
The temperature in the ISA tropopause is-
- 56 degrees C
Normally the diurnal range of temperature is greatest at -
an inland location
Solar radiation passing through the atmosphere is -
absorbed, scattered, reflected
The diurnal variation of temperature is -
the temperature pattern over a 24 hour period
On an ISA day you would expect the temperature at an elevation of 4000 ft above MSL to be-
7 deg
The sea level temperature in the standard atmosphere is -
15 deg
Q7 The primary cause of weather is -
temperature differential
The change of temperature for an increase in altitude known as-
lapse rate
Q10 Our weather is due to the atmosphere being heated mainly by -
radiation from the earth
Q8 A line on a weather chart joining places having the same temperature is called an -
isotherm
Q9 Radiant energy arriving from the sun is termed -
insolation
