Extreme‐weather risk and the cross‐section of stock returns

open access: yesJournal of Risk and Insurance, Volume 93, Issue 1, Page 163-198, March 2026.
Abstract We document an extreme‐weather risk premium in the cross‐section of stock returns. Between 1995 and 2019, stocks of domestic U.S. firms with the most negative sensitivity to aggregate storm losses earned an annual excess‐return spread of more than 6 percentage points relative to those with the most positive sensitivity, a difference not ...

Poisson count time series

open access: yesJournal of Time Series Analysis, Volume 47, Issue 2, Page 279-303, March 2026.
This article reviews and compares popular methods, some old and some recent, that produce time series having Poisson marginal distributions. The article begins by narrating ways where time series with Poisson marginal distributions can be produced.

Deep Convection‐Driven Downward Transport of Trace Gases and Aerosols From the Free Troposphere to the Boundary Layer

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep convective clouds regulate Earth's energy and moisture budgets, yet their impact on the atmospheric boundary layer (BL) composition remains underexplored. Using long‐term observations from three mid‐latitude sites, we show that deep convection (DC) consistently enhances nighttime surface ozone and is often accompanied by modest increases ...

Corona Discharges Glow on Trees Under Thunderstorms

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Coronae, which are weak electrical discharges, have long been hypothesized to form on trees under thunderstorms, though never directly observed, characterized, or quantified. Using a newly developed instrument that measures ultraviolet emissions from coronae, the first direct observations and quantifications of coronae are presented for two ...
