We also note that the likelihood ridge levels off for larger parameter values, rather than approaching zero, such that the likelihood only depends on the λ / μ ratio and not on the individual parameters.
Moving westward for much of its existence to the south of a narrow subtropical ridge, an upper level high developed over the strengthening low level circulation early on June 19, which became a tropical depression that day.
Lim et al.[48] present a local-feature-based quality metric which computes orientation certainty level (OCL), ridge frequency, ridge thickness, and ridge-to-valley thickness ratio.
Within a weak steering environment between a mid-level ridge over northern Mexico and a mid-level ridge over the northern Caribbean Sea, Nate drifted slowly southwestward initially.
Mandibular width is defined as the distance between the right and left mandibular WALA ridge at the level of the mesio-buccal groove of first molars.
The heat pushed parts of the ridge above sea level, creating an archipelago that allowed the turtles--and probably many other species--to island-hop from Asia to North America.
Vera drifted northward until an upper level ridge forced the storm to the east, providing upper level outflow for Vera to strengthen to a typhoon on August 20.
Over the next 6-12 hours, the disturbance moved towards the southwest and hugged Vanua Levu's southeastern coast, under the influence of a mid level ridge of high pressure that was located to the southeast of the system.
Under the influence of a mid-level ridge over the northwestern Caribbean Sea and an upper-level ridge over the southwestern United States, the newly upgraded Erick tracked west-northwest parallel to the coastline of Mexico.
A mid-level ridge near Cape Verde and a mid to upper-level low pressure northeast of the Leeward Islands forced the depression to move north-northwestward at roughly 17 mph.
The depression traveled northward along the periphery of a mid-level ridge over Mexico and an unusually strong mid to upper-level trough situated over the Baja California Peninsula.
