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

Figure 3

(a) The simulated sea level pressure (solid line, unit hPa) and 850 hPa geopotential height (dotted line, unit gpm) filtered by Barnes filter at 1200 UTC 30 July 2008, and the filled (open) circle indicates the TC center determined by lowest SLP (geopotential height) while the filled square represents the observed TC center. (b) The observed track (observation), the track determined by SLP with Barnes filter (with filter), and the track determined by SLP without Barnes filter (without filter) for TC Fung-Wong after landing China mainland.
