Re‐Examining Historical Trends of Tropical Cyclone Frequency

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The short duration of high‐quality, reliable tropical cyclone (TC) observations limits our ability to detect long‐term trends. Here, we analyze TC frequency trends in the NOAA 20th Century Reanalysis (20CR) versions 3 and 2c over the 19th and 20th centuries.

Trends and Sensitivities of Low‐Cloud Cover and Top Height From Spaceborne Lidar Observations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Low clouds effectively cool the Earth by reflecting incoming solar radiation. Detecting low‐level clouds with passive satellite sensors can be ambiguous, whereas active remote sensing instruments directly measure cloud‐top height. Here, we analyze 14 years of spaceborne lidar observations to assess trends in the occurrence of low‐level clouds ...

Precipitation Over the Contiguous United States Is Coming From Farther Away Than in the Past

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Atmospheric moisture transport is an essential component of the Earth's water cycle, carrying water vapor thousands of miles and controlling which regions receive precipitation and which do not. Here, we employ atmospheric moisture tracking, applied to 35 years of reanalysis data to investigate decadal trends in atmospheric moisture transport ...

Entrainment‐Based Framework for Understanding Extratropical Moist Heat Extremes

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In summer, the atmosphere over extratropical continents is close to moist convective neutrality, whereby near‐surface moist static energy, MSEs ${\text{MSE}}_{s}$, is tightly constrained by free‐tropospheric saturation moist static energy, MSE500∗ ${\text{MSE}}_{500}^{\ast }$.
