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.
