Improved Verification And Analysis Of National Weather Service Point Forecast Matrices, Paul Fajman Jan 2011

Improved Verification And Analysis Of National Weather Service Point Forecast Matrices, Paul Fajman

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Verification is the process of determining the quality of forecast information. Office and personal forecast verifications are significantly lacking throughout the National Weather Service for many reasons. The primary reasons are that verification is time consuming, tedious, and monotonous. This research attempted to ease that process by creating new computer procedures to automate the verification process. The new procedures were tested using two years of forecasting data from November 2007 to November 2009 from the Omaha/Valley Weather Forecasting Office to serve as a framework for future verifications. Point Forecast Matrices (PFM) produced by the National Weather Service twice daily and …

Analysis Of Causes Of Icing Conditions Which Contributed To The Crash Of Continental Flight 3407, Frederick R. Mosher, Debbie Schaum, Chris Herbster, Tom Guinn

Applied Aviation Sciences - Daytona Beach

On February 12, 2009, at 10:20 p.m. EST, Continental Connection Flight 3407 from Newark to Buffalo crashed 5 miles short of the runway at Buffalo, killing all 49 people on board and one person on the ground. The National Transportation Safety Board (NTSB) is still investigating the crash, but preliminary reports show the airplane was experiencing icing conditions before the crash. Preliminary reports indicate that the pilot did not respond properly to the icing conditions, which contributed to the crash. However, the presence of the icing conditions which were significant enough to cause aircraft problems needs further investigation to determine …

Global Composite Of Volcanic Ash “Split Window” Geostationary Satellite Images, Frederick R. Mosher Jan 2008

Global Composite Of Volcanic Ash “Split Window” Geostationary Satellite Images, Frederick R. Mosher

Applied Aviation Sciences - Daytona Beach

Volcanic ash is exceptionally hazardous for jet aircraft in flight. Flying through ash can quickly damage the jet engines, causing surging, flame out and immediate thrust loss. Pilots can inadvertently penetrate volcanic ash clouds because airborne weather radar will not reflect off the small ash particles, and the visual appearance of an ash cloud may look very similar to an ordinary meteorological cloud. To aid pilots in avoiding ash cloud areas, the International Airways Volcano Watch (IAVW) agreements have developed under the guidance of the International Civil Aviation Organization (ICAO).


Day/Night Visible Satellite Images, Frederick R. Mosher Feb 2006

Day/Night Visible Satellite Images, Frederick R. Mosher

Applied Aviation Sciences - Daytona Beach

Visible satellite images are very helpful for a wide variety of users. In particular, they are helpful in identifying areas of clouds and fog for general aviation pilots who must fly within sight of ground. However, visible satellite images have several major drawbacks, such as at night the visible pictures are black. Another problem is that it is sometimes difficult to distinguish between high clouds and low clouds. While the infrared channel can be used at night, frequently the low clouds and fog are near the temperature of the ground, so low clouds do not show up well on infrared …


Modification Of Precipitation By Coastal Orography In Storms Crossing Northern California, Curtis N. James, Robert A. Houze Jr. Nov 2005

Modification Of Precipitation By Coastal Orography In Storms Crossing Northern California, Curtis N. James, Robert A. Houze Jr.

Applied Aviation Sciences - Prescott

This study compiles and interprets three-dimensional Weather Surveillance Radar-1988 Doppler (WSR-88D) data during a 2.5-yr period and examines the typical orographic effects on precipitation mainly associated with winter storms passing over coastal northern California.The three-dimensional mean reflectivity patterns show echo structure that was generally stratiform from over the ocean to inland over the mountains. The flow above the 1-km level was strong enough to be unblocked by the terrain, and the mean echo pattern over land had certain characteristics normally associated with an unblocked cross-barrier flow, both on the broad scale of the windward slopes of the coastal mountains and …

Quantification Of The Effects Of Data Denial And Limitation In Mm5 Initialization On Forecast Accuracy, Robert W. Evans Mar 2002

Quantification Of The Effects Of Data Denial And Limitation In Mm5 Initialization On Forecast Accuracy, Robert W. Evans

Theses and Dissertations

The current hub-and-spoke network in the European Theater is made up of locations built and organized around a Cold War threat. The threat of large-scale attrition warfare seems to have passed, and the threat of multiple, smaller scale contingencies has placed greater demands on the US military's ability to transport equipment and personnel to multiple locations simultaneously. This research effort utilizes a Multiple Objective Linear Programming (MOLP) model to analyze optimal hub locations in USEUCOM. The model used to analyze the network was developed in Microsoft Excel and followed MOLP techniques to determine the trade-offs between the two constructs of …

Crop performance and climatic records were collated for high production counties in South Dakota to evaluate the effects of temperature and precipitation on yields. The crops involved were corn, soybeans, sorghum, oats, spring wheat, and winter wheat. Records were compared for the period from 1965 to 1982. The computer data file for each county includes seven climatic parameters, dates of plant development, adjusted yield-and yield rank by year. The crop/climate record for the 17-year period was evaluated in sixteen counties per crop each year. Thus, 272 county x year observations were made for each crop, except for soybeans which involved …

Marine & Environmental Sciences Faculty Articles

A 200 year old brain coral, captured in Bermuda in 1976 was slabbed and x-rayed. Using the annual growth bands sequential, dated samples were taken over the entire growth period of the coral and analyzed for Δ14C, δ13C and δ18O. During the past 80 years atmospheric variations in Δ14C and δ13C due to human effects, such as release of bomb C-14 and dilution of both C-14 and C-13 by fossil fuel burning, are closely tracked by the coral. Prior to 1900 divergences between the coral and tree Δ14C …
