Hmmm....
Paul Domaille on ukweather said:Still not easy, although I am begining to think not lentics. looking at the charts for the 16th and 17th winds in the region are light and vary between east and west over the two days. There is quite a lot of fog in the region, especially on the 16th and to the north of the area on the 17th, this would limit visibility at the times the charts were made.Overall Visibility is given at between 6 and 10 milesover the two days. Given that Santa Cruz is about 20 miles offshore it is highly unlikely that he would have seen a lenticular formed from the island ( Santa Cruz has a max height of only 2430') especially as he was observing from a further 15/20 miles inland. Sea temps (going on todays readings which are probably lower than December's) would indicate that the sea temp was probably equal too or warmer than the land, in the synoptic setup my best guess would be for an offshore breeze , if any, which would make any lentic formation to the west of Santa Cruz (even further away from the observer. There isn also quite a difference between the temp and DP at the 2,400' level, +4.9c DP -15.6c at Santa Ana (Long Beach unavailable). If this were the same or similar at Santa Cruz in these light winds I would think it unlikely that Lentics would form.
