The research, conducted by scientist Kinya Toride at the University of Colorado Boulder (USA), in collaboration with the US National Oceanic and Atmospheric Administration (NOAA) and the University of Tokyo ( Japan ), was published in the journal Communications Earth & Environment.
According to research, as water evaporates, condenses, and moves through the atmosphere, the ratios of heavy isotopes such as deuterium and oxygen-18 change, leaving a trail of the origin and path of water vapor, a crucial factor in cloud and rain formation.
The research team used data from an infrared atmospheric interferometer (IASI) on a satellite to create long-term data series on isotopes in the mid-atmosphere. By incorporating this data into a forecasting model, the simulations of temperature, wind, and humidity were improved, and the accuracy of weather forecasts increased by up to 5 days.
This method also shows potential for improving forecasts of heavy rainfall events. The authors note that further refinement of observational data and computational models is needed before application.
