The LBM experiment results. a Anomalous heating contribution to the development of NWPSH. Plotted values are area-averaged surface pressure anomaly in the subtropical northwestern Pacific [15°–30°N, 130°–155°E] (black rectangle) as a response to the idealized heating in each grid with the background state in August. Positive values in each grid indicate that the enhancement of convective activity strengthens the anomalous anticyclone (AC′) over the northwestern Pacific, and vice versa. b Steady response of surface pressure (contours; unit: hPa) to the prescribed heating anomalies over 20°S–20°N, 30°E–150°W during the heavy rainfall period. Red, blue, and black contours denote positive, negative, and zero values, respectively. The vertically integrated heat source anomaly from the surface to 10 hPa is indicated by shaded grid boxes (unit: W m−2)
