1. This is commonly called the synoptic scale . 2. Dynamically these nearly geostrophic turbulent eddies are the oceanographic counterparts of the atmospheric synoptic scale . 3. There have been many hypotheses suggesting a link between synoptic scale features and secondary eyewall replacement. 4. It has been hypothesized that this synoptic scale internal forcing could lead to a secondary eyewall. 5. Wind shear is a mesoscale or synoptic scale weather features such as squall lines and cold fronts. 6. Wind shear itself is a mesoscale or synoptic scale weather features such as squall lines and cold fronts. 7. The following are sixteen occurrences of a lake modified synoptic scale cold front or " pneumonia front ". 8. As a note, tropical and subtropical cyclones are classified by National Hurricane Center as synoptic scale rather than mesoscale. 9. This mathematical model is run four times a day and produces synoptic scale medium-range models in general use. 10. The Hadley, Ferrel, and Polar cells operate at the largest scale of thousands of kilometers ( synoptic scale ).
