متن کاملApplication of Lightning in Predicting High Impact Weather
Recent research has indicated a strong correlation between total lighting data (both in-cloud and cloud-to-ground) and severe weather such as hail and high wind storms. The lightning activities preceding severe storms have certain characteristics in lightning flashes, such as high in-cloud (IC) flash rates in the storm formation stage. The greater volume of strong updrafts during a severe thund...
متن کاملPredicting Italian Wines Quality from Weather Data and Experts’ Ratings
In this paper we examine how the weather determines the quality of wines produced in the Barolo and Barbaresco regions of Italy. Since pricing data are not widely available for these wines, we measure wine vintage quality by a variety of subjective measures of quality taken from the published opinions of several experts.

متن کاملPredicting Peak Sector Occupancy with Two-Hour Convective Weather Forecasts
An important function of traffic flow management ensuring the number of aircraft entering a sector does not exceed the amount that can be safely controlled by the sector controller. One factor that makes this task difficult is the uncertainty of the impact of convective weather, as both the weather forecast and the impact given specific weather is uncertain. In this investigation, we study this...
