A central European program pursues regional extensive scientific and technical collaboration in the field of operational limited-area numerical modeling for regional and local weather research, forecasting, and applications. Limited-area numerical weather prediction (NWP) models are essential tools for regional and local weather prediction and atmospheric research. The development, implementation, and operational execution of a limited-area model (LAM) are demanding on both human and computer

range of climate models. The aim of PDRMIP is to perform a thorough investigation of the differences in the effects of anthropogenic and natural drivers on precipitation and extreme precipitation events. This will be accomplished based on five core simulations, with global perturbation to either anthropogenic or natural drivers of climate change, as well as six selected regional perturbation experiments. PDRMIP will in particular enhance our understanding of drivers of climate change other than CO 2

Sustained assessment of the climatic impacts of land use and land cover change is essential. Land use and land cover change (LULCC) plays an important role in the climate system. Many studies have documented the impacts of LULCC on local, regional, and global climate. The National Climate Assessment Report ( Melillo et al. 2014 ) identifies LULCC as a “cross cutting” issue of future climate change studies. This report, and the previous U.S. Climate Change Science Program strategic plan (2003

Empirical and modeling studies have provided strong evidence of dynamical and chemical coupling across the range of spatial and temporal scales inherent in the Earth system (e.g., Prinn 2012 ). Current chemical transport models, however, inadequately account for the two-way coupling of atmospheric chemistry with other Earth system components over the range of urban/local to regional to global scales and from the surface up to the top of the atmosphere. As a result, the predictability of local

-MET). The only exception was the last paper which was on the dynamics of El Niño presented by Fei-Fei Jin (UHM-MET). The second day of the conference focused on two of the most profound disastrous weather phenomena over Taiwan: typhoons and mei-yu, which is the regional frontal system in late spring that brings in frequent heavy rainfall. These two phenomena also act as major water resources for the island. These papers were presented by researchers with the aim of transferring the research findings and

as an important time scale for endeavors such as water, agricultural, and land use planning (e.g., Vera et al. 2010 ). The promise of decadal climate prediction is supported by observational evidence of decadal climate variability with significant regional impacts, the effects of anthropogenic and naturally forced climate change, evidence of potential skill from idealized predictability studies ( Collins et al. 2006 ; Boer 2011 ), and pioneering attempts at predictions obtained by initializing

Climate models project a general increase in the frequency and intensity of hydroclimate extremes at regional to global spatial scales during the twenty-first century ( Donat et al. 2017 ; Hirabayashi et al. 2013 ), which is expected to cause severe casualties and economic loss ( Ward et al. 2014 ). This enhancement of extreme events is due to increases in atmospheric water vapor and rates of ascent in clouds ( O’Gorman and Schneider 2009 ; Pfahl et al. 2017 ). Along with these climatic

) describe these systems, collectively, as sentinels of regional and global changes in climate, land use, and water resource management policy because they integrate the effects of multiple system drivers over broad spatial and temporal scales. Impacts from these changes, such as those documented by Clark et al. (2001) and Livingstone (2003) , range from shifts in the timing and intensity of freshwater inputs and pollutant loadings, to habitat and ecosystem disruption following the invasion and spread

Africa is highly vulnerable to adverse impacts of climate change such as increased temperatures, reductions in precipitation, and increased climate variability. In many regions, such as the Greater Horn of Africa (GHA), the effects of these changes are compounded by rapid population growth, high poverty levels, dependence on rain-fed agriculture, and low adaptive capacity. Given the great uncertainty in climate projections for the GHA, early warning systems that are robust to evolving climate

the water-related effects of changes in glacier mass balance and river runoff in western Himalayas. Given the research focus of the GLACINDIA project, the initial focus of the workshop was on glacier-related hydrological information. During stakeholder interactions the resulting discussion covered a much broader range of urgent climate change information needs for the Himalayan region. WORKSHOP FORMAT. In total, 30 stakeholders were invited to participate in the workshop. Among them, the minister
