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 ...

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 ...

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

Conceptual Analysis of Vortex Contributions to Rogue Wave Formation in the Agulhas Current

Journal of Marine Science and Engineering
Harmonic summation and amplification by winds blowing contrary to currents are known contributions to rogue waves in the region of the Agulhas current, but the causes of the observed wave steepness, asymmetric form, and non-breaking are poorly understood.

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 ...

Viruses in multi-scale ocean models: challenges and opportunities

Frontiers in Marine Science
While viruses affect the flow of elements and energy at a planet-wide scale through lysis, gene transfer, and metabolic reprogramming, they are yet to be included in planetary-scale models of ecosystem function and nutrient cycling.

Assessing the Performance of the Copernicus European Regional Reanalysis Dataset in Reproducing Extreme Weather Events in Poland

International Journal of Climatology, EarlyView.
Global reanalyses, for example ERA5 and ERA5‐Land, tend to misrepresent the local‐scale weather extremes due to the limited spatial resolution. In this paper CERRA shows clear and consistent improvements over ERA5 and ERA5‐Land in representing extreme temperature and precipitation in Poland, particularly for localized and short‐lived heavy rainfall ...

Oceanography: The Past: Oceanography: The Present and Future

Eos, Transactions American Geophysical Union, 1983
Oceanography is a young science, close to its historical roots, but it's maturing fast as “state‐of‐the‐art” technology and computer‐aided numerical modeling play an increasing role. Our ability to obtain, process, and analyze enormous volumes of data would stun an oceanographer of the 1930's.
