The Application of Barnes Filter to Positioning the Center of Landed Tropical Cyclone in Numerical Models

Figure 1

The sea level surface pressure ((a), hPa), 850 hPa geopotential height ((b), gpm), relative vorticity ((c), s⁻¹), and potential height ((d), m²⋅K⋅s⁻¹⋅kg⁻¹) simulated by WRF model at 1200 UTC 30 July 2008. The filled square represented the observed TC center and the filled circle indicated the point with minimum value (in (a) and (b)) or maximum value (in (c) and (d)) around observed TC center.
