Ocean Heat Content: Quotation
Metrics of hurricane-ocean interaction: vertically-integrated or vertically-averaged ocean temperature? J. F. Price Woods Hole Oceanographic Institution, Woods Hole, Massachusetts 02543, USA ..... The first ocean metric that took account of the subsurface ocean temperature, called upper Ocean Heat Content (OHC), was written down by Leipper and Volgenau (1972) almost forty years ago OHC(x, y) = ρoCp integral 0 - Z26 (Ti(x, y, z) − 26)dz, (3) and is today widely used in operational, hurricane forecasting (Goni and Trinanes, 2003; DeMaria et al., 2005; and see especially the informative, recent review by Mainelli et al., 2008). The leading factors, ρo=1025 kg m−3 and Cp=4.0×103 J kg−1 ◦C −1 are sea water density and heat capacity and the lower limit of integration is the depth of the 26◦C isotherm, Z26. The reference temperature, 26◦C, is an average (dry bulb) temperature in the subtropical atmospheric boundary layer and so Ti(x, y, z=0)−26 is a measure of the thermal disequ...
