The Extratropical Transition of Tropical Cyclones. Part I: Cyclone Evolution and Direct Impacts

2017 Extratropical transition (ET) is the process by which a tropical cyclone, upon encountering a baroclinic environment and reduced sea surface temperature at higher latitudes, transforms into an extratropical cyclone. ET is influenced by, and influences, phenomena from the tropics to the midlatitudes and from the meso- to the planetary-scales to extents that vary between individual events. Motivated in part by recent high-impact and/or extensively observed events such as North Atlantic Hurricane Sandy in 2012 and Western North Pacific Typhoon Sinlaku in 2008, this review details advances in understanding and predicting ET since the publication of an earlier review in 2003. Methods for diagnosing ET in reanalysis, observational, and model-forecast datasets are discussed. New climatologies for the Eastern North Pacific and Southwest Indian Oceans are presented alongside updates to Western North Pacific and North Atlantic Ocean climatologies.
Practical and intrinsic predictability of multi-scale weather and convectively-coupled equatorial waves during the active phase of an MJO
Journal of the Atmospheric Sciences
Yue Ying, Fuqing Zhang
2017 Through a series of convection-permitting regional-scale ensembles based on the Weather Research and Forecasting model, this study investigates the predictability of multiscale weather and convectively-coupled equatorial waves during the active phase of a Madden-Julian Oscillation (MJO) event over the Indian Ocean from October 12 to November 12, 2011. It is found that the practical predictability limit, estimated by the spread of the ensemble perturbed with realistic initial and boundary uncertainties, is as much as 8 days for horizontal winds, temperature and humidity for scales larger than 2000 km which include equatorial Rossby, Kelvin, inertia-gravity and mixed Rossby-gravity waves.
Influence of Monsoonal Wind Speed and Moisture Content on Intensity and Diurnal Variations of the Mei-Yu Season Coastal Rainfall over South China
Journal of the Atmospheric Sciences
Xingchao Chen, Fuqing Zhang, Kun Zhao
2017 Convection-permitting numerical experiments using the Weather Research and Forecasting (WRF) Model are performed to explore the influence of monsoonal onshore wind speed and moisture content on the intensity and diurnal variations of coastal rainfall over south China during the mei-yu seasons. The focus of the analyses is on a pair of 10-day WRF simulations with diurnally cyclic-in-time lateral boundary conditions averaged over the high versus low onshore wind speed days of the 2007–09 mei-yu seasons. Despite differences in the rainfall intensity, the spatial distributions and diurnal variations of rainfall in both simulations verified qualitatively well against the mean estimates derived from ground-based radar observations, averaged respectively over either the high-wind or low-wind days.
Impact of the Diurnal Radiation Cycle on Secondary Eyewall Formation
Journal of the Atmospheric Sciences
Xiaodong Tang, Zhe-Min Tan, Juan Fang, Y Qiang Sun, Fuqing Zhang
2017 The sensitivity of the secondary eyewall formation (SEF) of Hurricane Edouard (2014) to the diurnal solar insolation cycle is examined with convection-permitting simulations. A control run with a real diurnal radiation cycle and a sensitivity experiment without solar insolation are conducted. In the control run, there is an area of relatively weak convection between the outer rainbands and the primary eyewall, that is, a moat region. This area is highly sensitive to solar shortwave radiative heating, mostly in the mid- to upper levels in the daytime, which leads to a net stabilization effect and suppresses convective development.
Isentropic analysis on the intensification of Hurricane Edouard (2014)
Journal of the Atmospheric Sciences
Juan Fang, Olivier Pauluis, Fuqing Zhang
2017 An isentropic analysis technique is adopted in this study to investigate the intensification of Edouard (2014) predicted by an experimental real-time convection-permitting hurricane analysis and forecast system. This technique separates the vertical mass transport in terms of equivalent potential temperature (θe) for the rising air parcels at high entropy from the subsiding air at low entropy. It is found that, as Edouard intensifies, the vertical circulation becomes wider via the expansion of upward (downward) mass flux to higher (lower) θe.
