Synoptic-Scale Precursors to Tropical Cyclone Rapid Intensification in the Atlantic Basin

Figure 1

24-hour pressure changes for the full Atlantic Basin hurricane database. Note that all pressure changes for all storms were resampled 10000 times to yield bias corrected and accelerated confidence intervals (shaded). Negative values imply 24-hour pressure decreases (in red) and positive values are 24-hour pressure rises (blue). The red shaded region was used to select the definition of RI in this study (25 hPa of pressure decrease in 24 hours).
