Juliana Dias is a research physical scientist at the Physical Sciences Laboratory (PSL) of the NOAA Earth System Research Laboratories in Boulder Colorado. Her main interests include coupling between tropical convection and the large-scale atmospheric circulation, tropical-extratropical interactions, equatorial waves dynamics, and predictability of the atmosphere on daily to sub-seasonal time scales. Her work is focused on various aspects of tropical sub-seasonal variability, tropical-extratropical interactions and on how those impact sub-seasonal predictions. Juliana's current projects include developing model diagnostics aimed at improving model's representation of tropical variability and understanding origins of tropical forecast errors as well as their impacts in extratropical subseasonal predictions.
