Cold Bias Stalls Kuroshio Engine for the Powerful Storms Hitting the North American West Coast

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “North Pacific model biases influence Kuroshio Extension atmospheric circulation patterns” by Song et al. (2026). A new research by Song et al. (2026) explores how sea surface temperature (SST) biases in climate models disrupt the predicted atmospheric circulation patterns caused by the Kuroshio Extension (KE). By... Continue Reading →

A 40-Year Hindcast Archive of U.S. Atlantic and Gulf Storm Surge and Wave from Landfalling Hurricanes

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on a preprint article “Tropical cyclone-driven storm surge and wave database for the US North Atlantic and Gulf coastlines” by Deb et al. (2026). This publicly available database provides a comprehensive hindcast of storm surge and wave conditions for 232 impactful tropical cyclones that struck the U.S.... Continue Reading →

Oceanic Slow-Lane: Why the Subtropical Gyre Holds the Key to How the ITCZ Responds to AMOC Slowdown

This blog post, created by NotebookLM, is based on “On the Atlantic extratropical-tropical teleconnection in response to external freshwater forcing” by Joshi an Zhang (2026). This research study utilizes a coupled climate model to investigate how a massive influx of freshwater in the North Atlantic triggers a chain reaction that shifts the Intertropical Convergence Zone (ITCZ) southward. The authors demonstrate that... Continue Reading →

A Collapse Of The AMOC Would Drastically Alter Global Monsoons

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Impacts of AMOC Collapse on Monsoon Rainfall: A Multi‐Model Comparison” by Ben-Yami et al. (2024). Summary: Ben-Yami et al. (2024) analyzes how a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC) would drastically alter tropical monsoon rainfall patterns worldwide. By...

How a Weakening Atlantic Ocean Circulation Is Rewriting South America’s Weather

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Impacts of a Reduced AMOC on the South America Mean Climate and Extremes” by Meccia & Blázquez (2025). Summary: This study investigates how a weakening Atlantic meridional overturning circulation (AMOC) influences the climate and weather extremes of South America. Utilizing the EC-Earth3 climate...

More Than an Emission: How Rising Waste Heat Are Cooking North America

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Energy‐Consumption‐Induced Anthropogenic Heat Release Intensifies Heatwaves and Wildfire Threats in North America: A CESM2‐Based Projection for the Late 21st Century” by Wang et al. (2025). When we talk about climate change, the conversation almost invariably turns to greenhouse gases. Carbon dioxide,... Continue Reading →

Why Rising Seas Could Lower a Hurricane’s Peak Surge—But Drown a Wider Area

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Combined impacts of hurricane strengthening and global mean sea level rise on future Atlantic storm surge events” by Danso et al. (2025). It’s a scenario that seems frighteningly straightforward: as climate change causes sea levels to rise and hurricanes to strengthen,... Continue Reading →

Seasonal outlook of hurricane activity for five North Atlantic sub-basins

Seasonal hurricane outlooks, such as those issued by NOAA's Climate Prediction Center, Colorado State University (Klotzbach et al., 2017), European Center for Medium-Range Weather Forecasts, and University of Arizona (Davis and Zeng, 2019), produce skillful (i.e.,. better than climatology) seasonal forecasts of overall North Atlantic tropical cyclone (TC) activity. Such forecasts are possible because seasonal... Continue Reading →

Synergy effect of warm Atlantic-Pacific on the longest-lasting 2023 western North American heat wave

The southwestern United States (US) and Northern Mexico experienced their longest stretch of record-breaking heat wave in the summer of 2023 from mid-June to early August, affecting over 100 million people, causing over 200 deaths, and $14.5 billion in economic loss. In Phoenix, Arizona, for example, the heat wave lasted for 31 days from 30... Continue Reading →

Onset of 2025 Atlantic Niña and its implication for typhoon landfalling risks in East and Southeast Asian countries

Atlantic Niña is a natural climate pattern characterized by cooler-than-average sea surface temperatures in the eastern equatorial Atlantic Ocean, appearing predominantly in June-August. It is considered the 'cold phase' of the Atlantic Zonal Mode, the leading mode of tropical Atlantic sea surface temperature variability in June-August, similar to how La Niña is the cold phase...
