Topology of The Polar Vortex and Montana Weather
Joshua Dorrington, Sushovan Majhi, Atish Mitra +4
This paper explores the use of Topological Data Analysis (TDA) to investigate patterns in zonal-mean zonal winds of the Arctic, which make up the polar vortex, in order to better e…
Detecting the Indian Monsoon using Topological Data Analysis
Enrique Alvarado, Daniela Beckelhymer, Joshua Dorrington +5
A monsoon is a wind system that seasonally reverses its direction, accompanied by corresponding changes in precipitation. The Indian monsoon is the most prominent monsoon system, p…
Through a Jet Speed Darkly: The Emergence of Robust Euro-Atlantic Regimes in the Absence of Jet Speed Variability
J. Dorrington, K. Strommen
Euro-Atlantic regimes are typically identified using either the latitude of the eddy-driven jet, or clustering algorithms in the phase space of 500hPa geopotential height (Z500). H…
Beyond skill scores: exploring sub-seasonal forecast value through a case study of French month-ahead energy prediction
Joshua Dorrington, Isla Finney, Tim Palmer +1
We quantify the value of sub-seasonal forecasts for a real-world prediction problem: the forecasting of French month-ahead energy demand. Using surface temperature as a predictor,…
