A database of monthly climate observations from meteorological stations is constructed. The includes six elements and extends over the global land surface. checked for inhomogeneities in station records using an automated method that refines previous methods by incomplete partially overlapping detecting with opposite signs different seasons. development reference series neighbouring stations. Information sources about a single may be combined, even without period, series. Thus, longer record...

Global change will alter the supply of ecosystem services that are vital for human well-being. To investigate service during 21st century, we used a range models and scenarios climate land-use to conduct Europe-wide assessment. Large changes in land use typically resulted large supply. Some these trends may be positive (for example, increases forest area productivity) or offer opportunities "surplus land" agricultural extensification bioenergy production). However, many increase...

Regional climate prediction is not an insoluble problem, but it a problem characterized by inherent uncertainty. There are two sources of this uncertainty: the unpredictability climatic and global systems. The system rendered unpredictable deterministic chaos; renders uncertain through external forcings imposed on system. It commonly inferred from differences between models regional scales that deficient, such inference premature; due to unresolved combination model deficiencies. Since...

Abstract Crowdsourced observation networks are typically much more dense than those maintained by National Meteorological Services, and sample a wider range of local climates. This offers an opportunity to build observed climatologies that representative lived experience, particularly in cities. study provides worked example show their potential for improving operational climate services, identify the challenges realizing potential. To demonstrate concept, data from personal weather...

Changes in climate pose major challenges to society, and so decision-makers need actionable information inform their planning policies make society more resilient climatic changes. Climate services are being developed provide such information. The successful development use of benefits greatly from close engagement between developers, providers, users the services. Science for Service Partnership China (CSSP China) is a China-UK collaboration fostering closer scientists, providers services,...

A prototype climate service was developed and trialled in early 2019 to provide seasonal forecast of the June-July-August (JJA) tropical cyclone (TC) landfall risk for East China region ahead forthcoming typhoon season. Test forecasts were produced both March April a final released Meteorological Administration (CMA) on 1 May 2019. The trial by using Met Office Global Seasonal system (GloSea5), western Pacific subtropical high (WPSH) index used infer TC based simple linear regression between...

Abstract The Conway–Maxwell–Poisson distribution improves the precision with which seasonal counts of tropical cyclones may be modeled. Conventionally Poisson is used, assumes that formation and transit result a process, such their frequency has equal mean variance (“equi-dispersion”). However, earlier studies observed records have sometimes found overdispersion, where exceeds mean, indicating are clustered in particular years. evidence presented here demonstrates at least some this...

Crowdsourced observations have the potential to bring a step-change in urban climatology. This rapid prototyping project explores their for improving standard observed grids, and likely consequences climate services.
