Predictability of European winter 2020/2021: Influence of a mid‐winter sudden stratospheric warming
Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022 Boreal winter 2020/2021 was characterised by a negative North Atlantic Oscillation (NAO) pressure pattern, yet the signals from the ensemble mean of many seasonal forecast systems were for a positive NAO. In this letter we focus on the GloSea5 seasonal forecast system and investigate if there is any evidence for forecast error, or whether the ...

Upper‐level midlatitude troughs in boreal winter have an amplified low‐latitude linkage over Africa
Atmospheric Science Letters, Volume 24, Issue 1, January 2023., 2023 Composite mean anomaly of 850‐hPa temperature at 10–15° N 2 days after the strongest midlatitude upper‐level trough days. The troughs are located at the longitude shown on the x‐axis, and the temperature is measured 16.5° longitude downstream (east) of the trough. Black dots indicate statistical significance.

Canadian contributions to environmetrics
Canadian Journal of Statistics, Volume 50, Issue 4, Page 1355-1386, December 2022., 2022 Abstract This article focuses on the importance of collaboration in statistics by Canadian researchers and highlights the contributions that Canadian statisticians have made to many research areas in environmetrics. We provide a discussion about different vehicles that have been developed for collaboration by Canadians in the environmetrics context as ...

Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract A changing climate is altering ecosystem carbon dynamics with consequences for natural systems and human economies, but there are few tools available for land managers to meaningfully incorporate carbon trajectories into planning efforts. To address uncertainties wrought by rapidly changing conditions, many practitioners adopt resistance and ...

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 175-190, January 2023., 2023 Abstract Decision‐making for pesticide registration by the US Environmental Protection Agency (USEPA) relies upon crop‐specific scenarios in a tiered framework. These standard modeling scenarios are stated to represent “…sites expected to produce runoff greater than would be expected at 90% of the sites for a given crop/use.” This study developed a ...

Forecasting low‐frequency macroeconomic events with high‐frequency data
Journal of Applied Econometrics, Volume 37, Issue 7, Page 1314-1333, November/December 2022., 2022 Summary High‐frequency financial and economic indicators are usually time‐aggregated before computing forecasts of macroeconomic events, such as recessions. We propose a mixed‐frequency alternative that delivers high‐frequency probability forecasts (including their confidence bands) for low‐frequency events.
