Climate and weather realizations are essential inputs for simulating crop growth and yields to analyze the risks associated with future conditions. To simplify the procedure of generating weather realizations and make them available over the Internet, we implemented novel mechanisms for providing weather generators as web services, as well as a mechanism for sharing identical weather realizatio...

Delays caused by uncertainty in weather forecasts can be reduced by improving traffic flow management decisions. This paper presents a methodology for traffic flow management under uncertainty in convective weather forecasts. An algorithm for assigning departure delays and reroutes to aircraft is presented. Departure delay and route assignment are executed at multiple stages, during which, upda...

BACKGROUND Medial ulnar collateral ligament (UCL) reconstruction is a common procedure performed on Major League Baseball (MLB) pitchers with symptomatic UCL insufficiency, frequently due to overuse. Warm weather climates afford youth pitchers the opportunity to throw year-round, potentially placing them at risk for overuse elbow injuries. PURPOSE/HYPOTHESIS To determine whether the proportio...

1. INTRODUCTION † The primary cause of national airspace delay is convective weather. A large fraction of these delays is due specifically to en route weather (Allen et al., 2001). Crowded travel corridors such as the Great Lakes corridor from Chicago to New York experience the most significant en route convective weather delays. It is of particular importance within these high traffic regions ...

We have extended an analytical workload model for estimating en route sector capacity to include the impact of convective weather. We use historical weather avoidance data to characterize weather blockage, which affects the sector workload in three ways: (1) Increase in the conflict resolution task rate via reduction in available airspace, (2) increase in the recurring task load through the rer...

The level of information on biometeorologic reports and mood effects of weather conditions on the Zagreb population were assessed in a sample of 782 subjects. Only 103 (13.2%) study subjects had not been informed on biometeorologic reports. Mood effects of weather conditions were reported by more than 76% of study subjects, 18.3% of them reporting meteorosensitivity. Meteorosensitivity showed a...

Harsh weather can have devastating effects on both the survival and the breeding success of wild animals. Corticosterone, released in response to the stress caused by harsh conditions, may trigger physiological and behavioral changes that help ameliorate these effects. We examined three species of Arctic-breeding passerine birds for correlations between circulating plasma corticosterone levels ...

Weather forecasting is a complex process that involves numerous specialized fields of expertise. The output from computationally intensive numerical weather prediction (NWP) models forms the starting point of the forecasting process. Expert forecasters have both a general knowledge of large-scale weather systems and specific knowledge about the idiosyncratic behavior of local scale weather phen...

A case has been presented in this paper for the use of spatial statistical techniques in analyzing crash data to investigate spatial patterns and spatial autocorrelation. “Weather-related” crashes in Wisconsin, aggregated on a county level, have been analyzed using spatial statistical techniques. The Getis-Ord Gi * statistic was used to identify spatial patters of different types of weather-rel...

The effective management of convective weather in congested airspace requires decision support tools that can translate weather information available to air traffic managers into anticipated impact on air traffic operations. The Convective Weather Avoidance Model (CWAM) has been under development at Lincoln Lab under sponsorship of NASA to develop a correlation between pilot behavior and observ...
