1 Variations in power input to the ocean using a recent global “reanalysis” extending back 2 to 1871 shows a strong trend in the net power input since then, a trend dominated by 3 the Southern Ocean region. This trend is interpreted as a spurious result of the changing 4 observational system. Focussing therefore, on the North Atlantic, where the data base is 5 somewhat more secure, the input po...

One of the most adverse weather phenomena in Catalonia are thunderstorms producing severe weather phenomenon like heavy rainfalls, hail storms, or tornadoes. Sometimes, these thunderstorms seem to have marked paths although in some cases these trajectories vary sharply, changing completely the movement directions that have previously followed, either breaking into several cells, or joining into...

Central Oklahoma is undergoing investment in new intermodal transportation and rehabilitation of its infrastructure. Despite a highly variable historical climate, future changes resulting from anthropogenic climate change may be outside the range for which infrastructure was designed. We examined 21st century trends, focusing on weather extremes demonstrated importance to professionals as ident...

John Balbus Climate change is not just a problem for rivers and reservoirs that are running dry, or forests and grasslands that are seeing an increased incidence of wildfire, or Arctic wildlife stressed by rapidly changing ecosystems. It’s a problem for human health, too, as John Balbus discusses with host Ashley Ahearn. It can be tricky to attribute specific health effects to climate change, w...

Modern troposphere delay models like the Vienna Mapping Functions (VMF1) are based on data from Numerical Weather Models (NWM) with a time resolution of typically 6 hours. Different from purely analytical formulations like the Global Mapping Functions, the VMF1 can account for real weather phenomena like changing high and low pressure systems and are thus more accurate. Additionally, the zenith...

Despite hazard mitigation efforts and scientific and technological advances, extremeweather events continue to cause substantial losses. The impacts of extreme weather result from complex interactions among physical and human systems across spatial and temporal scales. This article synthesizes current interdisciplinary knowledge about extreme weather, including temperature extremes (heat and co...

Distributed collaborative adaptive sensing (DCAS) of the atmosphere is a new paradigm for detecting and predicting hazardous weather using a dense network of short-range, low-powered radars to sense the lowest few kilometers of the earth’s atmosphere. DCAS systems are collaborative in that the beams from multiple radars are actively coordinated in a sense-and-respond manner to achieve greater s...

Several studies were devoted to investigating the effects of meteorological factors on the occurrence of stroke. Regression models had been mostly used to assess the correlation between weather and stroke incidence. However, these methods could not describe the process proceeding in the background of stroke incidence. The purpose of this study was to provide a new approach based on Hidden Marko...

A precise prediction of photovoltaic (PV) power has an important part to play as basis for operation and management strategies for a reliable and economical integration into the power grid. Due to fast changing weather conditions, e.g., clouds and fog, a precise forecast in the minute to hour range can be a difficult undertaking. But the growing IT-infrastructure allows a fine screening of PV p...
