A new scale‐selective measure of curvature for meteorological fields

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We introduce a novel diagnostic called curvature using radial variation (CURV) that quantifies the local cyclonic or anticyclonic curvature of mean‐sea‐level pressure or geopotential height gridded fields over selected scales. A depiction of how CURV values relate to differing cyclonic curvature is shown in the figure.

Subseasonal forecasts of the MJO and convectively coupled equatorial waves in ACCESS‐S2 and GraphCast: A multi‐year analysis

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
ACCESS‐S2 performs better in predicting longer time‐scale and slower moving waves (MJO and equatorial Rossby waves), while GraphCast performs better in predicting shorter and faster moving waves (Kelvin and mixed Rossby–gravity waves). However, both models systematically underestimate precipitation amplitude across all wave types, especially over the ...

Low‐order system for eddy growth in the storm track

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Reanalysis data for the North Atlantic storm track are used to construct a low‐order model that optimally fits the observed interaction between the mean flow and baroclinic eddies. The resulting model is a certain type of predator–prey model. It explains various properties of the storm track, including why eddies grow linearly with the Eady growth rate,

Investing Aura: Making Value at an Emirati Art Center

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT The article examines the politics and processes of establishing value for artworks, highlighting the continued belief in Walter Benjamin's idea of aura and describing the value aura generates as “auratic value.” Focusing on an artist residency program in the United Arab Emirates (UAE) during the country's arts boom, I analyze contestations ...

Cultivating and embracing plurality in abductive inquiries within strategy research

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Abduction offers a mode of scientific inquiry that focuses on formulating explanations for unexplained phenomena. By building a bridge between philosophy of science and strategic management research, this article offers a pluralistic view of abduction, highlighting abductive triggers as the starting point in seeking ...
