Observing Atmospheric Boundary Layer Property and Processes Associated Rapid Intensification in TCs
Abstract
Predicting the societal/economic and Navy operational impacts of a tropical cyclone (TC) critically depends on the successful predic tion of both its track and intensity. There has been a marked improvement in the TC track forecast in recent years, but a significan t challenge remains to skillfully forecast hurricane intensity changes, especially for Rapid Intensifications (RI). TC intensity is controlled through processes both external and internal to a storm. Internally, the interaction of the oceanic and atmospheric envir onments in the planetary boundary layer (PBL) plays a significant role in TC RI and is still poorly understood and simulated. Lackin g PBL observations within TCs limited our progress in related process understanding. The deployment of our Compact Raman Lidar (CRL) on the NOAA P-3 aircraft transfer our capability for TC PBL measurements. This fundamental research will use CRL TC PBL measurement s to advance our understanding of TC PBL processes, especially under conditions leading to TC RI. Our analysis will focus on the fol lowing four tasks: 1.Characterize TC PBL water vapor and temperature structure and variability.2.Document TC internal cloud structur e.3.Quantify sea spray aerosol distributions.4.Collaborate with other TCRI PIs on model evaluation and process study.
