These areas are sometimes frequented by cyclones moving poleward from tropical latitudes. Here coastal upwelling drives the eastern boundary current and an undercurrent that flows poleward. This tropical forcing generates atmospheric Rossby waves that have a poleward and eastward migration. Favourable sea surface temperatures of allowed Sepat to continue intensifying despite decrease of poleward outflow. They carry warm water from the tropics poleward. The combined flow of these gyres acts to advect the storm slowly poleward and westward. Species worldwide are moving poleward to colder areas. Throughout the rest of the day limited poleward outflow prevented linfa from intensifying. Warm fronts move poleward ahead of the cyclone path. The general trend in the atmosphere is for temperatures to decrease in the poleward direction. Also, they added that Roke developed a eye and a good poleward outflow channel. This is prominent poleward from 27th parallel south to 42nd parallel south. Poleward and upward elevation shifts have been observed already. Poleward of the Hadley cell a different pattern of circulation is observed. As it passes poleward of a location, hot and dry conditions develop.
