Research has shown that when the far eastern equatorial Pacific is cool and near the Dateline in the tropics surface water is warm there is a tendency in the upper air pattern over the subtropical western North Atlantic for a low pressure trough to form. This phenomenon is known as the tropical upper troposphere trough (TUTT). The TUTT pattern produces upper level shear suppressing tropical activity.
