Special Issue Information

Dear Colleagues,

With the ongoing global warming, the spatial-temporal characteristics of extreme hydrometeorological events such as flood, drought, and extreme heavy precipitation have changed at global and regional scales. These disruptive changes have caused significant impacts on economy, energy, ecology and human life and attracted extensive attention from many scholars worldwide. The in-depth understanding and accurate prediction of these events are critical to management's emergency response and the mitigation of negative impacts. However, regional geographical and climatic differences and the impact of human activities make it difficult to understand the complex mechanisms causing hydroclimatic extremes, which is further exacerbated by the interdependence and potentially destructive effects of risk factors. High-resolution regional climate models can capture the subtle variations of extreme precipitation from sub-hourly to seasonal scales through better representing convection and orographic forcing, effectively improving the accuracy of precipitation process simulation. Therefore, regional climate models play a key role in studying the complex impacts of climate change and human activities on extreme hydrometeorological events, and have been widely used in related studies. To this end, this Special Issue aims to gather the most important contributions to theoretical developments and scientific advances related to hydroclimatic extremes and impacts in regional climate modeling. Major topics of interest include, but are not limited to:

  1. Historical, current and future hydroclimate detection and attribution studies based on regional climate models and observations.
  2. Coupling modeling, assessment, improvement, and uncertainty analysis of regional climate models and hydrological models.
  3. Regional climate model applications in hydroclimatology, including the assessment and prediction of the impact of climate change on extreme hydroclimatic events such as floods, droughts, and heavy precipitation.
  4. Studies of the impact of human activities such as agricultural irrigation, soil and water conservation, water transfer projects, and afforestation on regional-scale extreme hydroclimate events.
  5. Measures and suggestions for mitigating or responding to extreme hydroclimatic events under climate change.

Understanding the variations in the water regimes of wetland ecosystems is crucial to analyzing the dynamics of wetland habitats under different water management policies and recharge conditions. A MIKE21 hydrodynamic model was constructed to simulate changes in the water level and flood extent from 1 May 2014 to 9 October 2014 in the Zhalong National Nature Reserve using field measurements, a digital elevation model (DEM), radar images, and climatic, meteorological, and land-use/land-cover data. The hydrodynamic model was calibrated and validated by water levels derived from hydrological gauge stations and water level loggers and the flooding extent was derived from multi-temporal synthetic aperture radar (SAR) images in different periods to evaluate the suitability of the hydrodynamic model for simulating wetland hydrological processes. The results demonstrated that the hydrodynamic model could simulate changes in the water level and flooding of the wetlands in the entire hydrological year. Accurate simulations were obtained for both calibration and evaluation with high correlations between the simulated and observed water levels. The simulated fine-scale hydrological regimes of semi-enclosed floodplain wetlands could be used to understand the ecohydrological processes affected by different water resource allocation schemes.

In this research, we explored rainfall variability in the Sogamoso River Basin (SRB), its relationship with multiple scales of variability associated with El Niño–Southern Oscillation (ENSO), and the implications for rainfall prolongation during multiyear La Niña events. First, we examined time-frequency rainfall variations in the SRB based on the standardized precipitation index (SPI) from 1982 to 2019, using wavelet transform and principal component analysis (PCA). In addition, we applied wavelet analysis to investigate the links at different time scales between ENSO and the main mode of rainfall variability in the SRB. Finally, we explored the role that each scale of variability played in the prolongation and intensity of rainfall in the SRB during the 1998–2000 and 2010–2012 multiyear La Niña events. The results of the wavelet analyses revealed significant ENSO relationships affecting SRB rainfall at three different scales: quasi-biennial (2–3-years) between 1994 and 2002, as well as from 2008 to 2015; interannual (5–7 years) from 1995 to 2011; and quasi-decadal (9–12 years) from 1994 to 2012. This indicates that multiyear events are a consequence of the interaction of several scales of variability rather than a unique scale. During the 1998–2000 event, El Niño conditions were observed during the first half of 1998; subsequently, a cooling of the central and eastern tropical Pacific (western tropical Pacific) on the quasi-biennial (interannual) scale was observed during 1999; in 2000, only La Niña conditions were observed on the interannual scale. Therefore, during this event, the quasi-biennial (interannual) scale promoted wet conditions in the Caribbean, the Andes, and the Colombian Pacific from June–August (JJA) 1998 to JJA 1999 (during 1999–2000). During the 2010–2012 La Niña event, the interbasin sea surface temperature gradient between the tropical Pacific and tropical North Atlantic contributed to strengthening (weakening) of the Choco jet (Caribbean low-level jet) on the quasi-biennial scale during 2010, and the interannual scale prolonged its intensification (weakening) during 2011–2012, acting to extend the rainy periods over most of the Colombian territory. Variations on quasi-decadal scales were modulated by the Pacific decadal oscillation (PDO), resulting in a further intensification of the 2010–2012 La Niña event, which developed under conditions of the cold PDO (CPDO) phase, whereas the 1998–2000 La Niña occurred during the transition from warm (WPDO, 1977–1998) to cold (CPDO, 2001–2015) conditions. These results indicate that the interaction of quasi-biennial to quasi-decadal scales of variability could play a differential role in the configuration and prolongation of rainfall events in the SRB.
