The weather diagram shows a low‑pressure centre L surrounded by concentric isobars at 1000 hPa, 1020 hPa and 1040 hPa. A cold front (CF) is currently 120 km west of point X and moves eastward at 30 km h⁻¹. A warm front (WF) is 80 km south of point X and moves northward at 20 km h⁻¹. Point X lies 50 km east of the low‑pressure centre. Assuming the map is for the Northern Hemisphere, answer the following:

(a) What is the present wind direction at point X?
(b) After 6 hours, what type of weather is most likely to be experienced at point X?

Point X lies 50 km east of the low‑pressure centre. Assuming the map is for the Northern Hemisphere, answer the following:

(a) What is the present wind direction at point X?
(b) After 6 hours, what type of weather is most likely to be experienced at point X?

Accepted Answer

(a) Southerly wind (from north to south). (b) After 6 h the area will have experienced the passage of both fronts, bringing cooler, likely rainy conditions followed by clearing and milder air.
