The potential flow model for a storm is represented by the superposition of a sink and a vortex. The stream function can be written in the (r,0) system as ψ=-(Λ/(2π))θ+(Γ/(2π))ln r, where Λ=Γ=100 m2/s. Assume a constant air density of 1.2 kg/m3 The gauge pressure at a distance of 100 m from the storm eye is
