An improved independent precipitation data set with the horizontal resolution of 7×7 km grid over central Europe was generated (Free University of Berlin (FUB)precipitation analysis). For scale dependent evaluation of the Local model (LM) of the German Weather service, the precipitation data were separated into convective and stratiform fractions. To analyse precipitation amounts an interpolati...

Background. High quality reporting of endoscopic procedures is critical to the implementation of colonoscopy quality assurance programs. Objective. The aim of our research was to (1) determine the quality of colonoscopy (CS) reporting in "usual practice," (2) identify factors associated with good quality reporting, and (3) compare CS reporting in open-access and non-open-access procedures. Meth...

The modulation of the North Pacific storm track by tropical convection on intraseasonal time scales (30– 90 days) in boreal winter (December–March) is investigated using the NCEP–NCAR reanalysis and NOAA satellite outgoing longwave radiation (OLR) data. Multivariate empirical orthogonal function (MEOF) analysis and case compositing based upon the principal components (PCs) of the EOFs reveal su...

OF DISSERTATION Moist Synoptic Transport of CO2 Along Midlatitude Storm Tracks, Transport Uncertainty, and Implications for Flux Estimation Mass transport along moist isentropic surfaces on baroclinic waves represents an important component of the atmospheric heat engine that operates between the equator and poles. This is also an important vehicle for tracer transport, and is correlated with e...

We present Particle Flurries, a case study of our efforts toward a synoptic visualization of pulsatile 3D flow that strives to show viewers all flow features simultaneously. The contributions are: a flow visualization technique for stereo viewing that quickly shows particle flow details throughout a volume; a novel poisson-based seeding strategy that prevents redundancy in the particle visualiz...

In the vast Low Nutrient Low-Chlorophyll (LNLC) Ocean, the vertical nutrient supply from the subsurface to the sunlit surface waters is low, and atmospheric contribution of nutrients may be one order of magnitude greater over short timescales. The short turnover time of atmospheric Fe and N supply (<1month for nitrate) further supports deposition being an important source of nutrients in LNLC r...

Observed regional rainfall characteristics can be analyzed by examining both the frequency and intensity of different categories of rainfall. A complementary approach is to consider rainfall characteristics associated with regional synoptic regimes. These two approaches are combined here to examine daily rainfall characteristics over the Australian region, providing a target for model simulatio...
