A statistical-dynamical downscaling procedure for global climate simulationsSpringer Science and Business Media LLC - Tập 50 - Trang 117-131 - 1995
F. Frey-Buness, D. Heimann, R. Sausen
A statistical-dynamical downscaling procedure for global climate simulations is described. The procedure is based on the assumption that any regional climate is associated with a specific frequency distribution of classified large-scale weather situations. The frequency distributions are derived from multi-year episodes of low resolution global climate simulations. Highly resolved regional distrib...... hiện toàn bộ
Synoptic patterns of atmospheric circulation associated with intense precipitation events over the Brazilian AmazonSpringer Science and Business Media LLC - Tập 128 - Trang 343-358 - 2015
Eliane Barbosa Santos, Paulo Sérgio Lucio, Cláudio Moisés Santos e Silva
The objective of this study is to characterize the atmospheric patterns associated with the occurrence of intense precipitation events (IPE) in different sub-regions of the Brazilian Amazon. Intense rainfall cases over six sub-regions were selected from a precipitation data set for the period from 1983 to 2012. The composition technique was used to characterize the prevailing atmospheric patterns ...... hiện toàn bộ
Retrieval and applications of atmospheric motion vectors derived from Indian geostationary satellites INSAT-3D/INSAT-3DRSpringer Science and Business Media LLC - - 2020
Sanjib K. Deb, Dineshkumar K. Sankhala, Prashant Kumar, Chandra M Kishtawal
The atmospheric motion vectors (AMVs) from Indian geostationary meteorological satellites are derived operationally at Space Applications Centre (SAC), Ahmedabad. Over the years, many improvements in the operational retrieval algorithm have taken place with the advancement in the retrieval techniques as well as in the sensors. Two Indian geostationary meteorological satellites INSAT-3D and INSAT-3...... hiện toàn bộ
Modeling the effects of changes in air temperature and precipitation on heterotrophic respiration in the central Tibetan PlateauSpringer Science and Business Media LLC - Tập 149 - Trang 451-464 - 2022
Yongjie Pan, Suosuo Li, Xia Li, Yingsha Jiang
Soil heterotrophic respiration is a major flux of CO2 from terrestrial ecosystems and plays an important role in the feedback between climate and the terrestrial carbon cycle. Numerous studies have shown that the melting of permafrost and frozen soil as a result of global warming is accelerating the release of CO2 from soils by microbial decomposition in cold regions, such as the Tibetan Plateau (...... hiện toàn bộ
Long-term climatic water availability trends and variability across the African continentSpringer Science and Business Media LLC - Tập 146 - Trang 1-17 - 2021
Charles Onyutha
This study analyzed trends and variability in climatic water availability (CWA) across the African continent using monthly precipitation and potential evapotranspiration (PET) over the period 1901–2015. Climatic water availability was characterized in terms of precipitation minus PET totals. Predictability of the variation in CWA was tested using climate indices. Large positive values of the CWA (...... hiện toàn bộ
Testing and improving type 1 error performance of Şen’s innovative trend analysis methodSpringer Science and Business Media LLC - Tập 142 - Trang 1015-1025 - 2020
Sadık Alashan
Recent Şen innovative trend analysis method (Şen_ITA) has high graphical visual ability in addition to quantitative trend identification analysis aspects. However, it is important to determine critical trend values as to whether they are significant according to a certain statistical significance level. In order to achieve such a goal, a certain amount or average percentages (5%, 10%, and 20%), bo...... hiện toàn bộ
