Andrea Marcheggiani

I am a trained physicist and I have been working in weather and climate science since 2017. My research interest focus on atmospheric dynamics and thermodynamics in time scale ranging from mesoscale and synoptic to decadal.

My PhD work focused on heat flux peaks in the atmosphere, which involved quantifying the effect of air-sea thermal coupling on baroclinic development, both in reanalysis data and in numerical simulations, while also investigating the driving mechanisms behind peaks of meridional heat flux.

• The role of heat-flux–temperature covariance in the evolution of weather systems (Marcheggiani & Ambaum, 2020)
• The life cycle of meridional heat flux peaks (Marcheggiani et al., 2022)

After my PhD I was briefly involved in the ACSIS project (funded by NERC, UK), assessing the predictability of the North Atlantic eddy-driven jet on decadal time scales.

• Decadal Predictability of the North Atlantic Eddy‐Driven Jet in Winter (Marcheggiani et al., 2023)

Currently I am a postdoctoral research assistant within the BALMCAST NFR project, where I am working to qualitatively and quantitatively assess the role that moist diabatic processes play in the evolution of midlatitude storm tracks.

• Diabatic effects on the evolution of storm tracks (Marcheggiani & Spengler, 2023)
• Spatio-temporal filtering of jets obscures the reinforcement of baroclinicity by latent heating (Auestad et al., 2024, in press)
• Weather features maintain the North Atlantic storm track (Marcheggiani et al., in preparation)
