We analyse climate variability in the North Atlantic sea-air fluxes derived from the voluntary observing ship (VOS) data and NCEP/NCAR Reanalysis. An ensemble of VOS climatologies has been produced in by the cross-application of different parameterizations and variable corrections. Interannual to decadal scale variability in both VOS and NCEP/NCAR fluxes is primarily determined by the turbulent...

BACKGROUND Major abdominal surgery (MAS) is associated with increased morbidity and mortality. The main objective of our study was to evaluate the predictive value of heart-rate variability (HRV) concerning development of postoperative complications in patients undergoing MAS. The secondary objectives were to identify the relationship of HRV and use of vasoactive drugs during anesthesia, intens...

[1] A recent paper (Paltridge et al., 2009) found that specific humidity in the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/ NCAR) reanalysis declined between 1973 and 2007, particularly in the tropical mid and upper troposphere, the region that plays the key role in the water vapor feedback. If borne out, this result suggests potential problems ...

Abstract The Weather Research and Forecasting (WRF) Model is a numerical weather prediction model supported by the National Center for Atmospheric (NCAR) to worldwide community of users. In recognition growing use cloud computing, NCAR now supporting in environments. Specifically, has established WRF setups with select service providers produced documentation tutorials on running cloud. Describ...

Abstract. The Organization of Tropical East Pacific Convection (OTREC) field campaign investigated the dynamical structure convection in tropical east and Caribbean. One central data sets for this is thermodynamic atmosphere measured by dropsondes released from NSF/NCAR G-V research aircraft. Between 7 August 2 October 2019, 648 were successfully 22 flights. Soundings launched a grid pattern wi...

Since 2003 the National Center for Atmospheric Research (NCAR) has been running various experimental convection-allowing configurations of the Weather Research and Forecasting Model (WRF) for domains covering a large portion of the central United States during the warm season (April–July). In this study, the skill of 3-hourly accumulated precipitation forecasts from a large sample of these conv...
