Hydrologic models of watersheds often represent complex systems which are difficult to understand regarding to their structure and dynamics. Virtual watersheds, i.e. watersheds which exist only in the virtual reality of a computer system, are an approach to simplify access to this real-world complexity. In this study we present the virtual watershed KIELSHED-1, a 117 km2 v-shaped valley with gr...

Two organizations within the National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service (NWS) are responsible for disseminating critical information to their customers prior to and during severe weather. The Storm Prediction Center (SPC) focuses on conducting an overall assessment of the environmental conditions on the national scale, and issues the appropriate severe wea...

The current mountain pine beetle (MPB; Dendroctonus ponderosae) outbreak in the southern Rocky Mountains has impacted approximately 750 000 ha of forest. Weather and habitat heterogeneity influence forest insect population dynamics at multiple spatial and temporal scales. Comparison of forest insect population dynamics in two principal host species may elucidate the relative contribution of wea...

Road traffic safety is the result of a complex interaction of factors, and causes behind road vehicle crashes require different measures to reduce their impacts. This study assesses how strongly the variation in daily winter crash rates associates with weather conditions in Finland. This is done by illustrating trends and spatiotemporal variation in the crash rates, by showing how a GIS applica...

In recent years, the eastern part of China has suffered numerous large-scale continuous fog and haze, which seriously impact people’s production and life. In present research, a combination method of questionnaire and experiment is used to discuss whether the hazy weather could influence the emotion and if there are any impacts on the work efficiency. 2 (gender) × 3 (emotional type: positive, n...

We examined expert meteorologists as they created a weather forecast while working in a naturalistic environment. We examined the type of external representation they chose to examine (a static image, a sequence of static images, or a dynamic display) and the kind of information they extracted from those representations (static or dynamic). We found that even though weather is an extremely dyna...

A detailed understanding of how the weather affects cycling is lacking. Where research has been carried out, focus often on temperate and hotter climates; little out regarding in colder climate communities. This study therefore investigated lived experience winter-season to provide empirical data for planning winter cold-climate Between 1 December 2017 30 April 2018, activities 13 cyclists (eig...

The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, includ...

The income-health gradient is a well-established finding in public health. This paper explores the gradient between income and different types of mortality: mortality that can be ameliorated via specific public policy measures, namely traffic fatalities, and mortality that is due to more “natural” causes, such as infectious disease. Using U.S. state-level data, growth in traffic mortality for 1...

The goal of this study was to evaluate associations between the meteorological conditions and the number of emergency cases for five distinctive causes of dispatch groups reported to SOS dispatch centre in Uppsala, Sweden. Center's responsibility include alerting to 17 ambulances in whole Uppsala County, area of 8,209 km2 with around 320,000 inhabitants representing the target patient group. So...
