1. Consider the sounding from Reno, NV at 1200 UTC, 13 Nov. 2000 below. Assume the upstream Sierra-Nevada mountain range is oriented in a north-south manner.

(a) Calculate the Scorer parameter (l) as a function of height up to 150 hPa. Include both terms in the calculation of l; could the one involving the vertical derivative of U have been neglected?

(b) If the orography is an infinite, sinusoidally varying set of mountain ranges separated in the east-west direction by 300 km, how does l compare to k as a function of height?
