Question

Compare the 500-mb and 300-mb wind flows. The pattern of wind directions also shows that the winds generally flow ________. This directional relationship is particularly evident at higher wind speeds.

a) parallel to the contour lines
b) perpendicular to the height contours
c) along the isobars
d) opposite to the height contours

Answer 1

The 500-mb and 300-mb wind flows move perpendicular to the height contours. This directional relationship is especially noticeable at higher wind speeds.

Step-by-step explanation:

The 500-mb and 300-mb wind flows refer to the wind patterns at the 500-millibar and 300-millibar pressure levels in the atmosphere, respectively. Both wind flows are influenced by the height contours and provide information about the direction and speed of the winds.

The pattern of wind directions at these pressure levels generally shows that the winds flow perpendicular to the height contours. This means that the winds move across the lines of equal pressure, from areas of high pressure to areas of low pressure.

This directional relationship is particularly evident at higher wind speeds, where the winds can cause significant changes in weather patterns and affect the movement of air masses.
