Juliana Dias is a research physicist scientist at the Physical Sciences Laboratory (PSL) of the NOAA Earth System Research Laboratories in Boulder Colorado. Juliana came to PSL as a CIRES and NRC postdoctoral research fellow from 2010 to 2013. She worked as a CIRES Research Scientist from 2014 - 2019, and joined NOAA in 2019. Her main interests include equatorial waves, the coupling between tropical convection and the large-scale atmospheric circulation, tropical-extratropical interactions, and predictability of the atmosphere on daily to seasonal time scales. Her work is focused on various aspects of tropical variability, tropical-extratropical interactions and on how those interact and impact subseasonal to seasonal predictions. Juliana’s current projects include developing model diagnostics aimed at improving predictions of subseasonal tropical variability, and assessing the impact of tropical forecast errors in extratropical subseasonal predictions.
