Extended Data Fig. 2. Remote versus local T′ generation during the 2021 Pacific Northwest heat wave.

Extended Data Fig. 2

Panels (a–d) as in Fig. 1. Panels (e–h) depict remotely generated T', advective T', adiabatic T' and diabatic T', respectively. The quantities have been computed by integrating Equation (1) along the respective trajectories between tg and te, whereby te is the first trajectory time step during which the respective air parcel was located closer than 500 km to its final position x(tX). Panels (i–l) show locally (that is, less than 500 km distance) generated T', advective T', adiabatic T' and diabatic T', respectively, computed as the difference between the top minus middle row. Panel (m) shows area weighted averages over the heat wave region (black line in panels a–l) for total T' and its contributions (that is, quantities shown in the top row) in red, as well as remotely and locally produced T' and its contributions (that is, quantities in the middle and bottom row, respectively) in blue and brown, respectively.
