Abstract

As described in Chap. 1, detection of TCs in operational practice may be subjective and sometimes controversial. That is also the case for detection of simulated TCs from model outputs. Research groups around the world have adopted TC tracking schemes using various techniques and threshold criteria. However, they are often not well explained [15]. Generally speaking, numerical tracking of TCs starts by locating a localized minimum in sea level pressure (SLP) or maximum in vorticity field to define the center of a potential TC. Then tracks are filtered by maximum wind speed, magnitude of vorticity, a measure of warm-core, and duration for which these criteria are met. Hereafter, for convenience, tracking schemes using these four parameters shall be referred to as base tracking. In addition to the base tracking parameters, some studies, especially those with high-resolution models, have adopted some measure of vertical variation of tangentional maximum wind speeds and horizontal temperature anomalies (referred to as structure criteria), genesis location criteria, and SLP anomaly thresholds
