Observations from three synoptic stations on the same day are given below: | Station | Latitude (°N) | Longitude (°E) | Altitude (m) | Pressure (hPa) | Temperature (°C) | |---------|---------------|----------------|--------------|----------------|-------------------| | A | 6°30'00" | 3°30'00" | 150 | 1005 | 28 | | B | 6°35'00" | 3°35'00" | 300 | 1000 | 26 | | C | 6°40'00" | 3°40'00" | 0 | 1010 | 30 | Use the hypsometric relation P₀ = P · exp(g h / (R T)) where g = 9.8 m s⁻², R = 287 J kg⁻¹ K⁻¹ and T is the absolute temperature (K). Answer the following:

Question Parts

( a )
Correct each station’s pressure to sea‑level pressure (P₀) and give the values to one decimal place.
( b )
Identify the station with the highest sea‑level pressure and state the likely wind direction between the stations with the highest and lowest sea‑level pressures (from high to low).
( c )
Using the coordinates of Stations A (6°30'N, 3°30'E) and C (6°40'N, 3°40'E), calculate the straight‑line distance between them (nearest kilometre) and then determine the temperature gradient (°C per kilometre) from A to C.
