|---|
| 584 | 590 | #### Explanation |
|---|
| 585 | 591 | |
|---|
| 586 | | -Isobars (lines of equal pressure) on surface charts indicate both wind direction and speed. Above the friction layer, wind flows parallel to isobars (geostrophic wind); close to the surface it crosses them at an angle toward lower pressure. Closely spaced isobars indicate a strong pressure gradient force and therefore strong winds; widely spaced isobars indicate light winds. Wind direction in the Northern Hemisphere is anticlockwise around lows and clockwise around highs (Buys-Ballot's Law). |
|---|
| 592 | +Isobars (lines of equal pressure) on surface weather charts reveal both wind direction and speed: |
|---|
| 593 | + |
|---|
| 594 | +- **Wind direction:** Above the friction layer (~600-1000 m AGL), wind flows parallel to isobars (geostrophic wind). Near the surface, friction causes the wind to cross isobars at 10-30 degrees toward lower pressure. In the Northern Hemisphere, wind blows anticlockwise around lows and clockwise around highs (Buys-Ballot's Law). |
|---|
| 595 | +- **Wind speed:** The pressure gradient force (PGF) drives wind from high to low pressure. Closely spaced isobars = strong gradient = strong winds. Widely spaced isobars = weak gradient = light winds. |
|---|
| 596 | +- **Why not the other options?** Hypsometric lines (A) show height contours on upper-level charts, not surface charts. Front lines (B) show air mass boundaries but do not directly indicate wind speed. Text annotations (C) may supplement but are not how wind is determined from the chart itself. |

| 2184 | 2206 | At high altitude, the wind is approximately geostrophic, blowing parallel to the isobars with low pressure to the left and high pressure to the right in the Northern Hemisphere. With low pressure to the north and high to the south, the pressure gradient force points northward, and the Coriolis deflection turns the resulting wind to the right — producing a westward (east-to-west) flow. The balloon is therefore carried toward the west. |
