Abstract Seasonal predictions have a great socioeconomic potential if they are reliable and skillful. In this study, we assess the prediction performance of SEAS5, version 5 seasonal system European Centre for Medium-Range Weather Forecasts (ECMWF), over South America against homogenized station data. For temperature, find highest performances in tropics during austral summer, where probability that correctly discriminate different observed outcomes is 70%. regions lying to east Andes,...
Abstract In the southern Peruvian Andes, communities are highly dependent on climatic conditions due to mainly rain‐fed agriculture and importance of glaciers snow melt as a freshwater resource. Longer‐term trends year‐to‐year variability precipitation or temperature severely affect living conditions. This study evaluates seasonal climatologies in period 1965/66–2017/18 for Andes using quality‐controlled homogenized station data new observational gridded data. this region, exhibits strong...
Abstract. Studies using climate models and observed trends indicate that extreme weather has changed may continue to change in the future. The potential impact of events such as heat waves or droughts depends not only on their number occurrences but also "how these extremes occur", i.e., interplay succession events. These quantities are quite unexplored, for past changes well future call sophisticated methods analysis. To address this issue, we use Markov chains analysis dynamics...
Abstract Precipitation deficits remain a concern to the rural population in southern Peruvian highlands and knowledge about their occurrence is lacking because of scarce data availability. For mountainous regions with sparse station networks, reanalyses can provide valuable information; however, known limitations reproducing precipitation are aggravated due unresolved topographical effects. In this study, we assess first step representation during rainy season (January–February–March) seven...
Abstract The rainy season is of high importance for livelihoods in the Southern Peruvian Andes (SPA), especially agriculture, which mainly rain fed and one main income sources region. Therefore, knowledge predictions such as its onset ending are crucial planning purposes. However, information currently not readily available local population. Moreover, an evaluation existing indices shows that they optimally suited SPA may be directly applicable a forecasting context. we develop new index,...
The development and dissemination of weather climate information is crucial to improve people's resilience adaptability variability change. impacts change are generally stronger for disadvantaged population groups due their limited adaptive coping capacities. For instance, smallholder farmers living in remote areas such as the southern Peruvian Andes suffer strongly from adverse climatic events droughts or frost. project Climandes aimed at providing high-quality services support agricultural...
Previous studies have found a pronounced nocturnal low-level jet at the exit of Inn Valley north valley contraction near Schwaigen which reaches into Alpine foreland (e.g. Pamperin and Stilke, 1985 as part MERKUR experiment or model study by Zängl, 2004). The forms under stably stratified atmospheric conditions is interpreted transition from subcritical to supercritical hydraulic flow. As pre-campaign TEAMx programme in June-August 2022, we conducted measurements corroborate...
