-level static stability and cold-point tropopause structure throughout Patricia’s RI. The cold-point tropopause is defined as the level of minimum temperature in a sounding ( Highwood and Hoskins 1998 ). This tropopause definition is widely used in the tropics because the cold-point temperature influences the exchange of ozone and water vapor between the troposphere and stratosphere ( Mote et al. 1996 ), which has important climatological implications ( Holton et al. 1995 ). Although few papers have

-Depression Investigation of Cloud-systems in the Tropics (PREDICT; Montgomery et al. 2012 ), have been conducted to obtain observations within various environments during the TC life cycle. These data have proven to be useful for understanding TC intensity changes. For instance, observational studies and model–observation comparisons based on these field campaigns (e.g., Black et al. 2002 ; Rogers et al. 2003 ; Houze et al. 2006 ; Jaimes et al. 2015 ) further proved the importance of vertical wind shear and sea

west-northwest of Bill, guiding the northern part of the outflow channel. We suggest that this upper-level trough, together with the strong upper-level easterlies in the deep tropics, contributed to Bill’s outflow channel ( Fig. 12a ). The 200-hPa horizontal wind speed in the Bill2 simulation also confirms that the outflow channel is the dominant feature at that time ( Fig. 12d ). Fig . 12.

) and boundary layer (below 800 hPa) are much sparser than those in the upper levels (above 400 hPa) in both cases ( Figs. 2b,d ). The lack of enhanced AMVs in the midlevel (700–400 hPa) is determined by the nature of the retrieval algorithm. Since the typical vertical distribution of AMVs in the tropics is highly bimodal (cirrus level and marine cumulus level) and the retrieved AMVs show higher vector errors between 700 and 400 hPa ( Sears and Velden 2012 ; Velden et al. 2017 ), the AMVs in this

ancillary effects of the block (II; between A and B). In this region, our analysis shows that the wind is subgeostrophic, and the environmental flow both curves to the left and slowly descends, acknowledging the limitations of geostrophic balance in the tropics. A bow wave is located ~1000 km beyond the outflow front. It represents the farthest extent of the TC where environmental winds return to geostrophic balance. As with the entire “atypical” RI process ( Part I ), this is a complex physical
