The synoptic chart shows a low pressure centre of 1000 hPa and a high pressure centre of 1025 hPa. Isobars are drawn 4 hPa apart, and the distance between successive isobars is 50 km. The chart follows the Northern Hemisphere convention (wind blows parallel to isobars with low pressure to the left). Point X is located east of the low and north of the high. Determine the wind direction at point X (state the direction from which the wind blows) and calculate the magnitude of the pressure‑gradient force per unit mass at X, expressing your answer in N kg(^{-1}) and as a percentage of the standard value 1 N kg(^{-1}).

Answer Options

A. Westerly wind; pressure‑gradient force ≈ 0.0050 N kg⁻¹ (≈0.50 % of 1 N kg⁻¹)
Correct Answer B. Northerly wind; pressure‑gradient force ≈ 0.0067 N kg⁻¹ (≈0.67 % of 1 N kg⁻¹)
C. Southerly wind; pressure‑gradient force ≈ 0.0095 N kg⁻¹ (≈0.95 % of 1 N kg⁻¹)
D. Easterly wind; pressure‑gradient force ≈ 0.0080 N kg⁻¹ (≈0.80 % of 1 N kg⁻¹)
Correct Answer
B
Correct Option:
Northerly wind; pressure‑gradient force ≈ 0.0067 N kg⁻¹ (≈0.67 % of 1 N kg⁻¹)
