Bedrock geology of the northern Columbia Plateau and adjacent areas [PDF]

The Columbia Plateau is surrounded by a complex assemblage of highly deformed Precambrian to lower Tertiary continental and oceanic rocks that reflects numerous episodes of continental accretion.

Characteristics of Intense Multi‐Day Wet Spells Over West Africa

International Journal of Climatology, EarlyView.
The study reveals a significant increase in intense wet spells, particularly in KASS‐D, emphasising the value of dense rain‐gauge networks. Larger‐sized events have grown, while smaller ones declined, boosting 3‐day and 5‐day wet spells' contribution to annual rainfall, with the Guinea Coast showing the highest increase and the Sahel the lowest ...

Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

International Journal of Climatology, EarlyView.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Trends and Circulation Conditions of Precipitation Over the Sudeten Mountains (Central Europe) in the Years 1961–2020

International Journal of Climatology, EarlyView.
Significant trends of precipitation totals are visible at seasonal (negative in spring and positive in winter) and monthly level. The deepening rainfall deficit in April in Western Sudetes threatens the stabilisation of forest ecosystems, the preservation of biodiversity and significantly limits water resources for economic use.

Upper- and mid-mantle interaction between the Samoan plume and the Tonga-Kermadec slabs [PDF]

, 2016
Mantle plumes are thought to play a key role in transferring heat from the core\u2013mantle boundary to the lithosphere, where it can significantly influence plate tectonics. On impinging on the lithosphere at spreading ridges or in intra-plate settings,

Warming Tropical Indian Ocean Wets the Tibetan Plateau

Geophysical Research Letters
AbstractAccurate detection and attribution of past climate change are crucial for projecting future climate change and formulating proper policies. In this study, we show that the warming of the tropical Indian Ocean contributes to the observed wetting trend in the Tibetan plateau. The warming tropical Indian Ocean can lead to more precipitation around

Assessing Past and Future Temperature‐ and Precipitation‐Based Indicators in the Republic of Yemen

International Journal of Climatology, EarlyView.
For the first time in the literature, this work assesses the past and future climatic trends over Yemen, a highly vulnerable country for which science‐based, high‐quality information for the development of climate change adaptation plans was not available until now.

Cordilleran Ice Sheet early deglaciation inferred from evolution of Late‐Pleistocene glacial Lake Dzulh Stun in east‐central British Columbia, Canada

Journal of Quaternary Science, EarlyView.
Abstract We document the early decay of the Late‐Pleistocene Cordilleran Ice Sheet in the central portion of the Rocky and Cariboo Mountains and the Rocky Mountain Trench in east‐central British Columbia. Glacial lakes impounded at the eastern margin of the ice sheet occupied watersheds on the west flank of the central Rocky Mountains, leaving ...
