Regional weather is affected by remote events. Jenney et al. [2019] present an index called STRIPES (Sensitivities To the Remote Influence of Periodic EventS) to quantify the remote impacts of quasi-period events on regional weather and climate. The index combines both spatial and temporal lag of the sensitivities. The authors applied this index to examine the variations of surface temperature, geopotential height, and precipitation in North America in relation to the Madden-Julian Oscillation, a tropical intraseasonal oscillation. It clearly identified what areas and what aspects of the regional weather climate are sensitive to the Madden-Julian Oscillation. Better insights into the spatial-temporal characteristics of remote impact are valuable for process understanding and prediction.
