Quantifying the Rightward Bias Extent of Tropical Cyclones' Cold Wakes

Abstract Although the cold wake of tropical cyclones (TCs) is recognized to be typically rightward biased relative TC track (in North Hemisphere), it remains unclear what extent bias should for specified TCs. Based on numerical simulations and observational statistics, this study shows that distance closely related latitude, translation speed radius maximum wind (RMW) a TC, but independent from surface radial profile outside RMW, namely intensity size. A semi‐empirical equation derived represent wakes. For TCs with slower speed, smaller or at higher latitudes, wakes are less asymmetric track. Atmospheric also show tends weaker more as closer center.
