Humpback Highs and Lows Amid Shifting Seas and a Northeast Pacific Marine Heatwave: Whale Demographics in the Main Hawaiian Islands, 2002–2023

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT North Pacific humpback whales are a celebrated conservation success, rebounding from extensive commercial whaling. Yet they remain vulnerable to the impacts of climate change, a multifaceted stressor that can exacerbate existing threats. During 2013–2016, a Northeast Pacific marine heatwave severely reduced forage availability in their feeding

Density and Abundance of Cetaceans in the Eastern Tropical Pacific Based on a Spatial/Temporal Analysis of 1986–2006 Line‐Transect Surveys

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The abundance of cetaceans in the eastern tropical Pacific Ocean (ETP) is estimated using spatial/temporal density modeling and conventional line‐transect approaches. Line‐transect data are analyzed from 10 ship‐based visual sighting surveys from 1986 to 2006 that include 281,000 km of survey effort in a 19.4 million km2 study area.

Co‐Occurring Weather Systems Vary by Atmospheric River Scale Across the United States

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Atmospheric Rivers (ARs) often co‐occur with other weather systems, including fronts, low‐pressure systems (LPSs), and mesoscale convective systems (MCSs), which can amplify precipitation and flood risk. While extreme rainfall is frequently linked to multiple interacting features, how these systems co‐occur with AR intensity scales and regions

Transition to Double‐Cell Mock Walker Circulations With Surface Warming Explained by Periodic Convection

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Idealized mock Walker simulations are widely used to study the interactions between overturning circulation and convection in the tropics. Previous studies documented a transition from a single‐cell to a double‐cell mock Walker circulation when the average sea surface temperature exceeds 300 K.

Characterization and Meteorological Drivers of Dust Events Over California's Central Valley

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Dust events in California's Central Valley pose severe risks to public health, regional air quality, and transportation. Yet, the climatology and meteorological drivers of dust events in the region are poorly characterized due to sparse monitoring and limitations of satellite observations.

Predicting and Explaining Lightning and Lightning‐Ignited Wildfires in Northern California With a Two‐Step Convolutional Neural Network Framework

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Lightning‐ignited wildfires (LIWs) are a major contributor to burned area in Northern California and have increased substantially in size over recent decades. Predicting LIWs remains challenging because ignition depends on both lightning occurrence and fuel‐meteorology interactions.

Different Last Millennium El Niño Southern Oscillation Sea Surface Temperature Patterns Drive Disparate North Atlantic Tropical Cyclone Characteristics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Understanding the relationship between the El Niño‐Southern Oscillation (ENSO) phenomenon and North Atlantic tropical cyclone (TC) activity is critical for both seasonal predictions and future projections of TCs. Unfortunately, the satellite observational era (1970‐present) captures too few El Niño events to fully characterize the response of ...

What Controls Extreme Rainfall Intensity and Location Associated With Line‐Shaped MCSs Over Northern Japan? An Ensemble‐Based Approach

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Line‐shaped mesoscale convective systems (MCSs) frequently produce extreme rainfall and severe hydrological disasters in Japan. This study investigates the environmental controls on both rainfall intensity and spatial displacement associated with two line‐shaped MCS events over northern Japan using convection‐permitting ensemble simulations ...
