This study examines the characteristics of a large number of extreme rain events over the eastern two-thirds of the United States. Over a 5-yr period, 184 events are identified where the 24-h precipitation total at one or more stations exceeds the 50-yr recurrence amount for that location. Over the entire region of study, these events are most common in July. In the northern United States, extr...

Updates to the Statistical Hurricane Intensity Prediction Scheme (SHIPS) for the Atlantic basin are described. SHIPS combines climatological, persistence, and synoptic predictors to forecast intensity changes using a multiple regression technique. The original version of the model was developed for the Atlantic basin and was run in near–real time at the Hurricane Research Division beginning in ...

We present a year-round assessment of the hydrographic variability within the East Greenland Coastal Current on the Greenland shelf from five synoptic crossings and 4 years of moored hydrographic data. From the five synoptic sections the current is observed as a robust, surface intensified flow with a total volume transport of 0.666 0.18 Sv and a freshwater transport of 426 12 mSv. The moorings...

We propose a new approach for analyzing multi-scale properties of the atmospheric flow that employs the recently introduced isentropic streamfunction and relies on its scale decomposition with Haar wavelets. We applied this method to a cloud resolving simulation of a planetary Walker Cell characterized by pronounced multi-scale flow. The resulting set of isentropic streamfunctions – obtained at...

A multiscale model of the MJO is developed here that accounts, in a simplified fashion, for both the upscale transfer from synoptic to planetary scales of momentum and temperature from wave trains of thermally driven equatorial synoptic-scale circulations in a moving convective envelope as well as direct mean heating on planetary scales. This model involves idealized thermally driven congestus ...

Fall-winter recurrence of current reversal from westward to eastward is identified on the Texas-Louisiana continental shelf using the current meter [Texas-Louisiana Shelf Physical Oceanography Program (LATEX-A)] and near surface drifting buoy [Surface Current and Lagrangian Drift Program (SCULP-1)] observations in 1993 and 1994. Reversal events roughly satisfy the Poisson distribution with one ...

Every patient with suspected or confirmed cancer requires accurate diagnosis and staging to guide treatment planning and to make informed patient care decisions. Physicians and surgeons have traditionally used narrative writing to report findings from investigative tests, surgical procedures and examination of tumour specimens. However, research has demonstrated that narrative reporting does no...

A one-layer, mid-latitudeJ beta-plane channel model of an incompressible homogeneous fluid is constructed to study the propagation of systematic errors on a nearly stationary synoptic scale wave. A timeand space-centered difference scheme is used to evaluate the governing primitive equations. Data fields resulting from height field perturbations injected at various locations in the synoptic wav...

Web-based synoptic reporting systems have been shown to improve efficiency, reduce turnaround time, and decrease reporting errors in reports of surgical pathology specimens and hematologic neoplasms and bone marrow. No such system has been previously described for the reporting of peripheral blood smears. We developed a Web-based synoptic reporting system composed of a knowledge base encompassi...
