The Convective Storm Initiation Project (CSIP) is an international project to understand precisely where, when, and how convective clouds form develop into showers in the mainly maritime environment of southern England. A major aim CSIP compare results very high resolution Met Office weather forecasting model with detailed observations early stages use newly gained understanding improve predictions model. large array ground-based instruments plus two instrumented aircraft, from U.K. National...
ABSTRACT A number of New World arenaviruses (Junín [JUNV], Machupo [MACV], and Guanarito [GTOV] viruses) can cause human disease ranging from mild febrile illness to a severe often fatal hemorrhagic fever syndrome. These highly pathogenic viruses the Old Lassa virus pose significant threat public health national security. The only licensed antiviral agent with activity against these viruses, ribavirin, has had mixed success in treating arenaviral is associated toxicities. novel pyrazine...
Gas-phase ozonolysis of alpha-pinene was studied in static chamber experiments under 'OH-free' conditions. A range multifunctional products-in particular low-volatility carboxylic acids-were identified the condensed phase using gas chromatography coupled to mass spectrometry after derivatisation. The dependence product yields on reaction conditions (humidity, choice OH radical scavengers, added Criegee intermediate NO(2)etc.) investigated probe mechanisms formation these products; additional...
The link between pollution and health is commonly explored by trying to identify the dominant cause of its most significant effect on outcomes. use multivariate features describe exposure less because investigating a large domain scenarios theoretically (i.e., interpretation results) technically computational effort) challenging. In this work we explore Bayesian Networks with approach probabilistic dependence structure environment‐health nexus. This consists environmental factors (topography...
This study investigated recent climate changes in Ghana and the relationships between malaria case rates. for 2008–2022. These were analysed at three spatial scales: national; regional; ‘climate zone’ (i.e., coastal, savannah forest zones that are roughly horizontal move south to north across Ghana). Descriptive statistics qualitative discussion used identify possible variability A correlation analysis was provide a quantitative framing of results. The...
This study investigated recent climate changes in Ghana and compared these to a new malaria case rates dataset for 2008–2022. The analysis was implemented at three spatial scales: national, regional, by ‘climate zone’ (i.e., coastal, savannah, forest zones). Descriptive statistics, qualitative discussion correlation were used compare the variability rates. identified general warming over period with mid-2010s maximum temperature peak savannah zones, also associated annual cycle. Malaria...
Managing the impacts of legacy waste from historic coastal landfills, contaminated land and artificial (made) ground is a pressing issue, given prevalence sites, their proximity to settlements or environmentally sensitive areas, risks associated with accelerating climate change (such as sea level rise increased erosion). At coast, these issues also fall between two largely separated policy areas – management on one hand, flood risk other which further complicates development...
The Republic of Kazakhstan, located in Central Asia, has experienced many years environmental degradation, largely as a result the poor management its significant natural resources. In this survey, data relating to different factors are critically analysed order understand state environment. It was found that: warming trends seen sensitive areas (e.g. steppe and near glaciers); drying where there is already water stress Aral Sea); air quality been declining recently (following improvements...
The UK has a well-established system of Chief Scientific Advisors (CSAs) who advise the Government on science relevant to policy development and implementation. There is also much more recently established group Thematic Research Leads (TRLs) support Parliament in their scrutiny activities. (Here, “Government” refers Prime Minister other Ministers run country with (very large) Civil Service; “Parliament” all Members (MPs) House Commons (HoC) Peers sit...
The mechanism of formation key compounds in atmospheric secondary aerosol (SOA) has been investigated by studying the products ozonolysis an enal derived from alpha-pinene using gas chromatography coupled to mass spectrometry.
Abstract An isolated thunderstorm formed in the southern United Kingdom on 15 June 2005 and moved through area where a large number of observational instruments were deployed as part Convective Storm Initiation Project. Earlier, convergence line had downstream Devon southwest southwesterly airflow, along which series light showers formed. The depth these was limited by capping inversion, or lid, at around 2.5 km. deep convection developed from one when broke lid ascended up to next...
Several arenaviruses can cause viral hemorrhagic fever, a severe disease with case-fatality rates in hospitalized individuals ranging from 15-30%. Because of limited prophylaxis and treatment options, new medical countermeasures are needed for these viruses classified by the National Institutes Allergy Infectious Diseases (NIAID) as top priority biodefense Category A pathogens. Recombinant consensus interferon alpha (cIFN-α) is licensed protein broad clinical appeal. However, while cIFN-α...
Abstract The effect on deep convection of large‐scale potential vorticity (PV) anomalies and their associated tropospheric stable layers is complex not well understood. This article examines the meteorological events 9 July 2007 (IOP7b Convective Orographically‐induced Precipitation Study (COPS)), which was dominated by an upper‐level PV anomaly that stretched from UK to southern France as far northeast Denmark. Three precipitation regions were identified case: lines intense storms beneath...
Abstract Upper‐level potential‐vorticity (PV) anomalies reduce the convective stability of troposphere through their impact on vertical potential‐temperature profile, thus reducing inhibition (CIN) and increasing available potential energy. Here, by contrast, we show a layer stable air that was intrinsically linked with an upper‐level PV anomaly increased CIN. This descended tracked beneath small anomaly, which in this case shallow trough. low‐humidity, relatively high‐PV originated from...
ABSTRACT Projected increasing temperatures and reduced summer rainfall in the United Kingdom pose a sustainability food security challenge for agricultural industry. This study investigates potential impact of precipitation changes on eastern England sugar beet yield. Precipitation data over from weather stations (1971–2000) range 5 th Phase Coupled Model Intercomparison Project ( CMIP5 ) climate models (‘historical’ 1971–2000; Representative Concentration Pathways RCP45 RCP85 2021–2050)...
• A good classification system, in addition to being reliable, must be easy use. This report examines the difficulties raters encountered using DSM-III diagnose 24 child and adolescent psychiatric case histories. Overall, reported few difficulties. They consistently preferred over DSM-II as more useful diagnostic system. In summarizing results of entire four-part study, we conclude that DSM-III, with additional refinement, gives promise a very usable reliable system for diagnosis disorders...
Precipitation delivery mechanisms for Dolleman Island (DI), located off the east coast of Antarctic Peninsula, are investigated using reanalysis and back trajectory data. The Southern Annular Mode (SAM) ENSO both shown to influence precipitation event size. variability is compared against interannual variation chemical data from two DI ice cores. Nitrate concentration in cores strongly linked with ratio easterly westerly trajectories arriving at DI, as described by a Cross‐Peninsula Index...
Abstract The Convective and Orographically‐induced Precipitation Study (COPS) campaign was conducted during the summer of 2007. A suite instruments housed at top Hornisgrinde Mountain (1156 m) in Black Forest region south‐west Germany provided datasets that allow an investigation into physical, chemical hygroscopic properties aerosol particles sampled COPS. Organic mass loadings were found to dominate composition for majority project, exceeding 8 µg m −3 a period high pressure, temperature,...
