, 2014
Selection of predictors for statistical downscaling is crucial as the relationship between the predictors (temperature, humidity and geopotential height) and predictands (local scale meteorological variables such as rainfall) forms the basis of ...

Surface and Tropospheric Climatic Trends in the Galápagos Archipelago Based on the Galápagos Archipelago Refined Analysis Dataset

International Journal of Climatology, EarlyView.
The Galápagos Archipelago's near‐surface climate is primarily influenced by interannual El Niño‐Southern Oscillation variability, with no statistical evidence for long‐term trends in air temperature, humidity, or precipitation. While tropospheric warming and increased atmospheric stability are observed, these trends are largely decoupled from near ...

A Zonal‐Meridional Projection Method for Quantifying Global Land‐Ocean Moisture Transport

International Journal of Climatology, EarlyView.
We present a physically consistent and computationally efficient method to quantify global coastal moisture transport by projecting vertically integrated moisture flux onto signed land–ocean boundary segments. The signed projection naturally distinguishes ocean‐to‐land inflow and land‐to‐ocean outflow without explicit directional classification ...

Downscaling of Temperatures Over the Eastern Mediterranean for the 21st Century

International Journal of Climatology, EarlyView.
We developed an analogue‐based statistical downscaling method, using a K‐nearest‐neighbour framework, to project daily maximum temperature (Tmax) and minimum temperature (Tmin) at 32 homogenized meteorological stations. Late twenty‐first‐century (2080–2100) temperature projections obtained using the method, show robust warming across all stations and ...

Reducing grid artifacts in air temperature downscaling with a Volume-Preserving interpolation preprocessing step

International Journal of Applied Earth Observations and Geoinformation
Statistical downscaling, including machine learning based downscaling, is widely used to produce high spatiotemporal resolution air temperatures for monitoring extreme heat events. However, coarse baseline data often exhibit sharp discontinuities at grid

Genetic Programming for the Downscaling of Extreme Rainfall Events on the East Coast of Peninsular Malaysia

Atmosphere, 2014
A genetic programming (GP)-based logistic regression method is proposed in the present study for the downscaling of extreme rainfall indices on the east coast of Peninsular Malaysia, which is considered one of the zones in Malaysia most vulnerable to ...

Satellite and Reanalysis Dataset Dependence of ETCCDI Extreme Precipitation Trends in Paraná, Southern Brazil

International Journal of Climatology, EarlyView.
Extreme precipitation trends detected in Paraná, Southern Brazil (1983–2024), are strongly conditioned by the dataset used, with reanalyses indicating coherent inland drying and longer dry spells, observations retaining stronger mesoscale heterogeneity, and satellite products often showing declines in short‐duration extremes. Monthly diagnostics reveal

Representation of Long‐Term Observed UK Winter Precipitation Trends and Variability in UKCP18 Global Climate Models

International Journal of Climatology, EarlyView.
Evaluating historical precipitation trends is complicated by interactions between variability in atmospheric circulation and thermodynamic forcing. This study assesses 1901–2023 UK winter precipitation trends in UK Climate Projections 2018 (UKCP18) global climate models using dynamical adjustment to separate circulation‐driven and non‐dynamical ...

Evaluating downscaled products with expected hydroclimatic co-variances [PDF]

Geoscientific Model Development
There has been widespread adoption of downscaled products amongst practitioners and stakeholders to ascertain risk from climate hazards at the local scale (e.g., ∼ 5 km resolution).

Automated regression-based statistical downscaling tool.

, 2008
Many impact studies require climate change information at a finer resolution than that provided by Global Climate Models (GCMs). In the last 10 years, downscaling techniques, both dynamical (i.e. Regional Climate Model) and statistical methods, have been
