Question 7

confluent flow picture

Answer 7

Question 8

diffluent flow picture

Answer 8

Question 9

divergence

Answer 9

an increase in the horizontal area of an air parcel causing shrinking in vertical due to change in speed down the flow

Question 10

diffluence

Answer 10

increasing separation of streamlines downstream, air slows down

the geostrophic wind is …………………….

Answer 12

non-divergent

Question 13

…………………………………………………………………..results from the ageostrophic component

Answer 13

any divergence or convergence and hence vertical motion

ageostrophic motion acts ………………………………………….. of the acceleration (in ………………. flow)

Answer 14

perpendicular and to the left

frictionless flow

Question 15

flow around curved contours is subject to ………………………………

Answer 15

acceleration towards the center of curvature

Question 16

flow around curved contours is subject to acceleration towards the center of curvature due to

Answer 16

an imbalance between the corriolis force and pressure gradient force

Question 17

flow around curved contours is subject to acceleration towards the center of curvature due to an imbalance between the coriolis force and pressure gradient force.

……………………………….. will lead to ageostrophic motion

Answer 17

the acceleration
