Juliana Dias is a research physical 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 coupling between tropical convection and the large-scale atmospheric circulation, tropical-extratropical interactions, equatorial waves, and predictability of the atmosphere on daily to sub-seasonal time scales. Her work is focused on various aspects of tropical variability, tropical-extratropical interactions and on how those impact sub-seasonal to seasonal predictions. Juliana's current projects include developing model diagnostics aimed at improving predictions of subseasonal tropical variability, assessing the influence of tropical forecast errors in extratropical subseasonal predictions, and investigating mesoscale air-sea interactions.
