IPS1501 Assignment 4 Year Module (Due: 28
August 2023)
1). Which of the following conditions would lead to a motion that is not geostrophic flow?
a. motion near the surface
b. being in the southern hemisphere
c. straight, parallel isobars
d. pressure gradient force cancels the coriolis force
e. the absence of friction
Ans: a. motion near the surface
Motion near the surface would be influenced by friction, so it would not be geostrophic
flow.
2). For geostrophic flow the wind moves parallel to the isobars with the lower pressures on the
_____ if you are looking in the direction the wind is blowing toward.
Ans: left
If you are looking in the direction of the wind then the lower pressures will be on the left.
3). Which wind flow is caused by straight isobars in the absence of friction?
Ans: geostrophic flow
Geostrophic flow does not occur for curved flow.
4). Which of the following is true for both geostrophic flow and gradient flow?
a. the pressure gradient force and coriolis force are not in balance.
b. the wind follows the isobars.
c. the isobars are curved.
d. wind blows in a straight line.
e. the speed of the wind changes.

, Ans: b. The wind follows the isobars.
Both geostrophic flow and gradient flow follow the isobars.
5). What is a hadley cell?
a. a large convection cell of ocean water that rises near the equator due to heating of water
b. a large convection cell of air that rises near the equator due to heating of air
c. a large convection cell of air that rises near the equator due to the coriolis effect
d. a large convection cell of ocean water that rises near the equator due to the coriolis
effect
Ans: b. a large convection cell of air that rises near the equator due to heating of air
6). What is the intertropical convergence zone?
a. the region of falling air and low pressure near the equator
b. the region of rising air and low pressure near the equator
c. the region of rising air and high pressure near the equator
d. the region of falling air and high pressure near the equator
Ans: b. the region of rising air and low pressure near the equator
7). What type of weather would you expect to encounter along the intertropical convergence
zone?
a. cloudy conditions and high rainfall
b. cloudy conditions and moderate rainfall
c. mixed cloudy and clear conditions and high rainfall
d. mixed cloudy and clear conditions and low rainfall
e. cloudy conditions and low annual rainfall
Ans: a. cloudy conditions and high rainfall
8). What features are found near the subtropical high-pressure systems?
a. large lake systems
b. large desert systems
c. large organic-material-rich systems
d. large rain systems
e. large coriolis systems
