Investigation Of Eddy Population And Motion In The Southern International Ice Patrol Operations Area (40°-47°N By 40°-55°W), Frank J. Williams Oct 1985

Investigation Of Eddy Population And Motion In The Southern International Ice Patrol Operations Area (40°-47°N By 40°-55°W), Frank J. Williams

OES Theses and Dissertations

A study of the eddy population in the Newfoundland Basin region over the period from November 1981 to December 1984 was conducted. The study was undertaken to demonstrate the importance and basic character of eddy motion in the area patrolled by the International Ice Patrol. This is a descriptive study and no rigorous mathematical solutions are attempted. Data was collected on the number of eddies in the area, their average duration and size, formation, migration and deterioration patterns and rotational velocity. Satellite infrared imagery maintained by National Weather Service and Naval Eastern Oceanographic Center, Canadian Forces METOC Center sea surface …

The Frontal Hydraulic Head: A Micro-Α Scale (~1 Km) Triggering Mechanism For Mesoconvective Weather Systems, M. A. Shapiro, Tamara Hampel, Doris Rotzoll, F. Mosher Jul 1985

The Frontal Hydraulic Head: A Micro-Α Scale (~1 Km) Triggering Mechanism For Mesoconvective Weather Systems, M. A. Shapiro, Tamara Hampel, Doris Rotzoll, F. Mosher

Publications

Measurements from the NOAA Boulder Atmospheric Observatory (BAO) 300 m tower, the National Center for Atmospheric Research (NCAR) Sabreliner aircraft, and the NOAA GOES-5 satellite, give evidence for the cross-front scale collapse of nonprecipitating surface cold-frontal zones to horizontal distances of ∼1 km or less. The leading edges of these frosts possess the characteristic structure of density current flows: an elevated hydraulic head followed by a turbulent wake. Vertical motions at the frontal heads exceed 5 m s−1 at 300 m (AGL). The ascent at the frontal head may act as a (∼1 km-scale) triggering mechanism for the release of …

Impacts Of Interactive Processing Systems On The Forecasting Ability Of The National Severe Storms Forecast Center (Appendix E), Frederick R. Mosher Apr 1985

Impacts Of Interactive Processing Systems On The Forecasting Ability Of The National Severe Storms Forecast Center (Appendix E), Frederick R. Mosher

Publications

The National Severe Storms Forecast Center (NSSFC) in Kansas City has the most modern interactive processing equipment of any operational forecast office in the United States. As such, the experiences of the NSSFC serve as the indication of some of the benefits which will be derived from interactive technology when it is applied in other forecast situations. The forecast products issued by the NSSFC have become more accurate and more timely. The forecaster's efficiency and productivity has noticeably improved. These improvements have been made without the introduction of any new data sources, any major advances in meteorology, or any major …

Functional And Performance Requirements Of The Next Noaa-Kansas City Computer System (Appendix G), Frederick R. Mosher Apr 1985

Functional And Performance Requirements Of The Next Noaa-Kansas City Computer System (Appendix G), Frederick R. Mosher

Publications

The NOAA computer system in Kansas City, Missouri, was scheduled for a computer upgrade and this is part of the report listing the critical functional and performance requirements for that system in 1984. The system needed to communicate with all the other offices at that center in Kansas City.

Lessons Learned From The Csis [Centralized Storm Information System] (Appendix D), Frederick R. Mosher, Joseph T. Schaefer Apr 1985

Lessons Learned From The Csis [Centralized Storm Information System] (Appendix D), Frederick R. Mosher, Joseph T. Schaefer

Publications

Various attempts have been made to give up-to-the-minute meteorological observations to forecasters. However, the meteorologist's inability to assimilate all the real-time data is a significant barrier to the improvement of short-term forecasts and warnings. Historically, failure to resolve this problem has plagued mesoscale forecast experiments. This article discusses the joint effort of NWS, NESS, NASA, and SSEC to develop a system to aid the forecaster in evaluating data.

Effects Of El Nino On Local Hydrography And Growth Of The Giant Kelp, Macrocystis Pyrifera, At Santa Catalina Island, California, Richard C. Zimmerman, Deborah L. Robertson Jan 1985

Effects Of El Nino On Local Hydrography And Growth Of The Giant Kelp, Macrocystis Pyrifera, At Santa Catalina Island, California, Richard C. Zimmerman, Deborah L. Robertson

OES Faculty Publications

Deepened isotherms associated with El Niño resulted in severe nutrient limitation and very low kelp productivity during the last half of 1983. Frond growth rates were so low that terminal blades formed before reaching the surface, eliminating the canopy. Frond initiation rates were also extremely low, resulting in significant reductions in mean plant size. Plants growing above 10m were more severely affected than plants at 20m. Nutrient pulses associated with internal waves are thus critical for survival of Macrocystis pyrifera in nutritionally marginal habitats in Southern California.
