Sudden stratospheric warmings (SSWs) can affect tropospheric weather and climate, while the factors affecting surface response to SSWs are not fully understood. This study shows important effects of preconditioned state on displacement split using ERA5 reanalysis historical simulations from 12 Coupled Model Intercomparison Project 6 (CMIP6) models. Both CMIP6 models show that signals (e.g., pos...

The effectiveness of greenhouse control can be improved by the application of model based intelligent control. Such control requires a good model of the greenhouse. For a large variety of industrial or recreational greenhouses the derivation of an analytical model is not feasible therefore black-box modeling has to be applied. Identification of black-box models requires large amount of data fro...

Air quality is heavily influenced by weather conditions. In this study, we assessed the impact of long-term weather changes on air quality and health in the US during 1994-2012. We quantified past weather-related increases, or 'weather penalty', in ozone (O3) and fine particulate matter (PM2.5), and thereafter estimated the associated excess deaths. Using statistical regression methods, we deri...

Severe climatic anomalies in summer 1816, partly due to the eruption of Tambora in April 1815, contributed to delayed growth and poor harvests of important crops in Central Europe. Coinciding with adverse socio-economic conditions, this event triggered the last subsistence crisis in the western World. Here, we model reductions in potential crop yields for 1816 and 1817 and address the question,...

Soil temperature can exhibit considerable memory fromweather and climate signals and is among the most important initial conditions in numerical weather and climate models. Consequently, a more accurate longterm land surface soil temperature dataset is needed to improve weather and climate simulation and prediction, and is also important for the simulation of agricultural crop yield and ecologi...

cornelia de lange syndrome (cdls) is an uncommon multiple congenital anomaly with unknown cause and recurrent risk and may be the result of an inheritance metabolic error. in classical form of the syndrome there is a recognizable facial appearance at birth although in children with mild disease this may be less obvious at birth but become more noticeable over the first three years of life. in t...

The importance of weather for tourism is now widely recognized. However, no research has so far addressed weather events from retrospective viewpoints, and, in particular, the role of “extreme” events in longer-term holiday memories. To better understand the character of ex post weather experiences and their importance in destination image perceptions and future travel planning behavior, this e...

Understanding the trend of localized severe weather under the changing climate is of great significance but remains challenging which is at least partially due to the lack of persistent and homogeneous severe weather observations at climate scales while the detailed physical processes of severe weather cannot be resolved in global climate models. Based on continuous and coherent severe weather ...

The effective management of traffic flows during convective weather events in congested air space requires decision support tools that can translate weather information into anticipated air traffic operational impact. In recent years, MIT Lincoln Laboratory has been maturing the Convective Weather Avoidance Model (CWAM) to correlate pilot behavior in the enroute airspace with observable weather...
