Analysis of Climate Variability of Homogeneous Regions of Rainfall Anomalies in Southeast South America (SESA)

International Journal of Climatology, EarlyView.
We studied rainfall variability and cyclicity in six Homogeneous Regions of Rainfall Anomalies (HRRA) in Southeast South America (SESA) from 1961 to 2020 to understand the occurrence of droughts and above‐average rainfall. We use a continental analysis scale, focusing on seasonal, interannual, and interdecadal cycles, and their association with modes ...

Decoupled lake history and regional moisture availability in the middle elevations of tropical Mexico

Revista Mexicana de Ciencias Geológicas, 2016
During the Holocene, most of the climatic variability in the tropics has manifested through changes in the precipitation regime. Although there is relatively a large amount of information on this climatic variability from the lowlands during this time ...

Degradation of Seasonally Frozen Ground in the Three–River Source Region and Its Correlation Impact Within Precipitation–Runoff Process

International Journal of Climatology, EarlyView.
This study reveals how climate change alters the water cycle in the Three Rivers Source region by degrading its important ‘solid groundwater’ (seasonally frozen ground). We found that runoff response varies by watershed and the role of permafrost decreases sharply, making water supply more dependent on rainfall and becoming increasingly vulnerable ...

Recording of ocean-climate changes during the last 2,000 years in a hypoxic marine environment off northern Chile (23°S) Registro de cambios océano-climáticos durante los últimos 2000 años en un ambiente marino hipóxico en el norte de Chile (23°S)

Revista Chilena de Historia Natural, 2000
Atmosphere-ocean interactions are particularly strong along the Chile-Peru coast and largely account for the extreme aridity of the Atacama Desert. Near the center of the driest part of this coastal desert, we found that the embayment Bahía Mejillones ...

Terrestrial Response to Maastrichtian Climate Change Determined from Paleosols of the Dawson Creek Section, Big Bend National Park, Texas

Geosciences
Climate during the Late Cretaceous is characterized by a long-term cooling trend interrupted by several periods of increased warming. This study focuses on the terrestrial response to two rapid climate events just prior to the K-Pg boundary marked by the

Projections of Meteorological Drought and Potential Evapotranspiration Using the RegCM4 Over Northeastern Iran

International Journal of Climatology, EarlyView.
We downscale CanESM2 with the Regional Climate Model version 4 (20 km) and evaluate against 15 stations to derive monthly PET (Hargreaves–Samani) and SPEI for northeastern Iran (1990–2009, 2040–2059, 2080–2099). Results show robust PET increases and a shift toward more negative monthly SPEI—especially April–September—indicating earlier onset and longer

Influence of the Scandinavian ice on the climate conditions of east plain European evidenced from the numerical simulation project PMIP II

Лëд и снег, 2015
In this paper results of climate simulation in East-European Plain (EEP) by coupled climate models (which take part in project PMIP II (Paleoclimate Modeling Intercomparison Project)) are tested for different climatic periods (pre-industrial, Last ...

Detection, Attribution and Projection of Precipitation Structure Changes Over Northwest China

International Journal of Climatology, EarlyView.
The precipitation structure shows a change trend of ‘the frequency of light precipitation decreased and the intensity of heavy precipitation increased’; attribution analysis shows that greenhouse gas forcing (GHG) is the main driving factor of precipitation structure change, and the model underestimates its impact, while aerosol forcing (AER) and ...
