High-resolution assessment of North Atlantic moisture transport in current climate and CMIP-6 future projections (SETESTRELO)

Summary:

Moisture transport is a dominant factor for changes in the hydrological cycle, with higher impacts on extremes rather than on averages.
There is no doubt that the risk of precipitation extremes and droughts is likely to increase with climate change, and the last IPCC report points to that global climate models are limited and need regional modelling. The central objective of this project is a high-resolution assessment of the moisture transport in the North Atlantic for current and future climates using ERA5 reanalysis and CMIP6 outputs with increased resolution through dynamic models adjusted to regional meteorology of the North Atlantic region. At to our knowledge, there are not studies using CMIP6 models and their new emission scenarios (RCPs-SSPs) to study the projection of moisture transport, its mechanisms as ARs and LLJs, and its relationship (dependence) with extremes of precipitation and droughts in future climates in the North Atlantic region; no regionalisations exists that use dynamic downscaling experiments for this purpose, and even less Lagrangian studies have been conducted to identify future changes in the sources and sinks of moisture, which are the focus of this project.
We will perform multiple dynamic downscaling experiments using the regional Weather Research and Forecasting (WRF) model for two regions, one centred on the North Atlantic Ocean and the other in Central America, using two nested domains (30 and 10 km of spatial resolution). WRF will be forced with ERA5 reanalysis and three CMIP6 Global Climate Models with three sets of simulations: the historical climatic conditions (1994-2014, also for ERA5), the conditions for the middle and end of the century (2040-2060 and 2080-2100), and two of the new scenarios -SSP2-4.5 and SSP5-8.5-. Then, to determine the historical and future extensions of major moisture sources located in the North Atlantic and the associated sinks over continents we will use the moisture transport the FLEXPART-WRFv3.3.2 Lagrangian model. The model will be forced with the forty different sets of high-resolution WRF outputs obtained in the dynamical downscaling to track the trajectory of atmospheric particles to calculate variations in specific humidity
along their pathways at high horizontal resolution. As the mechanisms of transport are crucial for impacts, we will determine changes in future climates of ARs and LLJs occurrence and their characteristics linked to the moisture transported by these systems. To understand how the hydrological cycle is altered by dynamic and thermodynamic processes related to climate change the determination of the residence time of water vapour in the atmosphere (WVRT) is a fundamental parameter. We will determine how changes in the WVRT (measured by several methods) influenced by changes in the large-scale circulation patterns modulate moisture transport and associated precipitation extremes in climate change hotspots in the North Atlantic region.
The more precise information about the high-resolution regional moisture transport and changes in the hydrological cycles from this project will make possible to distinguish the effects of impacts in the short, medium, and long term, and will be crucial for implementing early prevention and adaptation measures, reducing vulnerabilities, and mitigating potential risks.

Goal:

The general objective of this project is a high-resolution assessment of the moisture transport in the North Atlantic for current and future climates using ERA5 reanalysis and CMIP6 outputs with increased resolution through dynamic models adjusted to regional meteorology.

Hypothesis:

There is a need for address how moisture transport, its mechanisms, and its relationship with extremes of precipitation and droughts will change in the future climate.
