For most of its length, the eastern and western boundaries are clearly defined by land masses, except where it is separated from the Caribbean Sea and Gulf of Mexico by troughs and trenches. The northern and southern limits are more difficult to define. To the n...
متن کاملDeep Convection in the Ocean
SCIENTIFIC OBJECTIVES Issues specific to oceanic deep convection are the relatively strong role of rotation, such that convective Rossby numbers appropriate to the vertical motions may fall below unity; the highly intermittent nature of the forcing, with the strong impulses coming during the passage of atmospheric weather systems; the possible highly localized occurrence of deep convection; and...
