Folks love to talk about lenticular clouds, which are generally produced by air moving up (and down) downstream of a mountain barrier (see picture below). Such clouds are generally found in the lower atmosphere at or just above the crest level of the mountain barrier that produces them.

A Strong Surge of Marine Air Brings Relief to the Pollen Afflicted
During the past weeks, I have gotten several emails from folks with pollen-related allergies.
When will the suffering end they asked?
Early spring is the time of tree pollen, and the recent warm weather brought high values and substantial suffering to the sensitive.
As shown the pollen levels at Seattle for the last 30 days (below, from pollen.com), the values during the past several days reached a high level (red colors).
The rise began in late March, with several ups and downs. Ups during warm periods, downs in cooler periods with onshore flow of marine air.
Scientists predict the pollen for some trees, like birches in the Seattle area, will be eight times more abundant in our region by the end of the century, according to the state Department of Health.
The culprit? Climate change.
