description |
International audience Modeling tritium content in water presents a meaningful way to evaluate the representation of the water cycle in climate models as it traces fluxes within and between the reservoirs involved in the water cycle (stratosphere, troposphere, and ocean). In this study, we present the implementation of natural tritium in water in the atmospheric general circulation model (AGCM) MIROC5-iso and its simulation for the period 1979-2018. Owing to recently published tritium production calculations, we were able to investigate, for the first time, the influence of natural tritium production related to the 11-yr solar cycle on tritium in precipitation. MIROC5-iso correctly simulates continental, latitudinal, and altitude effects on tritium in precipitation. The seasonal tritium content peaks, linked to stratosphere-troposphere exchanges, are accurately simulated in terms of timing, even though MIROC5-iso underestimates the amplitude of the changes. Decadal tritium concentration variations in precipitation owing to the 11-yr solar cycle are well simulated in MIROC5-iso, in agreement with the observations at Vostok in Antarctica for example, Finally, our simulations revealed that the internal climate variability plays an important role in tritium in polar precipitation. Owing to its influence on the south polar vortex, the Southern Annular Mode enhances the effect of the production component on tritium in East Antarctic precipitation. In Greenland, we found an east-west contrast in the detection of the 11-yr solar cycle in tritium in precipitation owing to the influence of the North Atlantic Oscillation on humidity conditions. |
