In this data set, vehicle observations have been linked to data containing weather and road surface conditions. A total of 311 908 observations are collected and classified in categories of precipitation type, road status information, and daylight condition. The data is collected for a long period of time, so that several different weather situations are present, ranging from dry summer to adve...

This study investigated the impact of sea surface temperature (SST) on extreme precipitation events in North Japan and its relation to synoptic weather patterns using large-ensemble climate simulations. Eight were identified by applying cluster analysis level pressure anomalies for selected days with derived from a 3000-year historical experiment. Interannual variability associated two specific...

SURFEX is a new externalized land and ocean surface platform that describes the surface fluxes and the evolution of four types of surfaces: nature, town, inland water and ocean. It is mostly based on pre-existing, well-validated scientific models that are continuously improved. The motivation for the building of SURFEX is to use strictly identical scientific models in a high range of applicatio...

We present a code for automated detection, classification, and tracking of solar filaments in full-disk Hα images that can contribute to Living With a Star science investigations and space weather forecasting. The program can reliably identify filaments; determine their chirality and other relevant parameters like filament area, length, and average orientation with respect to the equator. It is...

On 21 July 2001 a number of severe storms developed over the region of Camaguey, Cuba, which were observed by radar. A numerical simulation was performed in order to realistically reproduce the development of the storms observed that day. The mesoscale model MM5 was used to determine the initial, boundary and update conditions for the storm-scale simulation with the model ARPS. Changes to the s...

Finding security vulnerabilities requires a different mindset than finding general faults in software thinking like an attacker. Therefore, security engineers looking to prioritize security inspection and testing efforts may be better served by a prediction model that indicates security vulnerabilities rather than faults. At the same time, faults and vulnerabilities have commonalities that may ...

atmospheric visibility has been defined as the greatest distance at which an observer can see a black object viewed against the horizon sky, which in quantitative terminology is known as visual range. visibility, in the absence of special meteorological events (e.g. rain and fog), is an excellent indicator of air quality. visibility impairment results from light scattering and absorption by atm...

Although weather has been shown to affect financial markets and financial decision making, a still open question is the channel through which such influence is exerted. By employing a multiple price list method, this paper provides direct experimental evidence that sunshine and good weather promote risk-taking behavior. This effect is present whether relying on objective measures of meteorologi...

Abstract The Weather Research and Forecasting (WRF) Model is a numerical weather prediction model supported by the National Center for Atmospheric (NCAR) to worldwide community of users. In recognition growing use cloud computing, NCAR now supporting in environments. Specifically, has established WRF setups with select service providers produced documentation tutorials on running cloud. Describ...

Using the recently developed PPMLR-MHD code, we present 3D global simulation of the interaction of the interplanetary (IP) shock with the magnetosphere with emphasis on the the effect of shock orientation. We investigate its impact on the sudden commencement (SC) of geomagnetic storms and the magnetospheric responses. Generally speaking, a highly oblique shock causes asymmetric compression of t...
