Fig. 4: Differences in the GPI and its components between compound MHW-TC and non-MHW events during late spring (April-May).
From: Compound marine heatwaves and tropical cyclones delay the onset of the Bay of Bengal summer monsoon
Spatial patterns of differences in (a) GPI, (b) Maximum potential intensity (\({V}_{{pot}}\)), (c) Absolute vorticity (η), (d) Vertical wind shear (\({V}_{{shear}}\)), (e) Relative humidity (Rhum), and (f) Vertical pressure velocity (ω). White oblique lines indicate areas where the differences are statistically significant at the 0.05 level based on the bootstrap hypothesis testing. g Differences in contributions from the total GPI term (purple left axis) and its associated components (black right axis), along with contributions from three anomalous \({V}_{{pot}}\) terms (black right axis), averaged over the defined study region (8-23°N, 84-92°E). White asterisks in the bars indicate signals exceeding the 0.05 significance level.
