; Ralph et al. 1997 ), there were remarkably few direct observations of rotors during the first four decades following the SWP and JSP. This situation has now changed as rotors have become the focus of new observational campaigns. In a recent study, the near-surface flow across and downwind of the Wickham mountain range on the Falkland Islands was observed during a field campaign aimed at improving the prediction of orographically generated turbulence ( Mobbs et al. 2005 ). Several strong downslope

, and three radar wind profilers. T-REX marks the first time such a suite of ground-based systems has been deployed to observe mountain waves and rotors. Rotors have been observed at numerous locations around the world such as the Rocky Mountains ( Lester and Fingerhut 1974 ; Darby and Poulos 2006 ), the Wickham Range on the Falkland Islands ( Mobbs et al. 2005 ), and the Sierra Nevada range ( Holmboe and Klieforth 1957 ; Kuettner 1959 ; Grubišić and Billings 2007 ). The Sierra Rotors Project

parallel with the major terrain features ( Kuettner 1958 , 1959 ), but their position varied with the time of day, being farthest downstream in late afternoon. Mobbs et al. (2005) conducted a detailed study of rotor flows in the lee of the Falkland Islands. A similar although simpler oceanic example can be seen in the internal hydraulic jump of the Mediterranean Outflow studied by Armi and Farmer (1988 , their Fig. 2.5, section 12) and Wesson and Gregg (1994) . In the case studied here, coherent
