All of these dates were associated with frontal passages and/or tropical disturbances.
The results of our study are consistent with perceptions in the literature (Lowery 1945, Dennis 1954, Gauthreaux 1971, Duncan 1994) and more anecdotal accounts that largest numbers of migrant birds stop over along the northern Gulf Coast when there is inclement weather to impede passage over or near the Gulf in spring, and in the tail winds immediately following cold frontal passages in autumn.
Like the Gulf, Tenney's crew is often put together on short notice, fishing on a weekday, because the chances of lining up that many favorable conditions after a frontal passage
, on a Saturday, remain sketchy.
The winter maximum primarily results from frequent frontal passages
and cyclogenesis in the western Gulf of Mexico (Saucier, 1949).
With regular frontal passages
occurring this month the winds can kick the seas up to where many of us would rather stay closer to shore.
