Figure 6

Objective analysis of geopotential height, temperature, and jet stream axes for 300 hpa on 27 March 1992/12:00 UTC. Geopotential contours: every 60 gpm, isotherms: every 2∘C, and jet stream axes denote wind speed more or equal to 30 ms^-1; T₁ and T₂ are trough lines and L₁ and L₂ the surface depression centres.
