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 →

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 →

The Atlantic’s Weakening Pulse: How a Slowing Ocean Current Could Reshape Our Climate and Coasts

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on "State of the Science Fact Sheet: Atlantic Meridional Overturning Circulation (AMOC)" by NOAA Science Council. This NOAA fact sheet briefly explains the Atlantic Meridional Overturning Circulation (AMOC), defining it as a critical ocean current that transports heat, salt, and carbon by... Continue Reading →

TWISO is a tropics-wide 45-day pulse and does not requires MJO

This blog post and the “Deep Dive” podcast on a paper “Tropics-wide intraseasonal oscillations” by Bao et al. (2025) was created by NotebookLM. Deep Dive Podcast “Earth's Global Climate Heartbeat The TWISO Cycle” powered by NotebookLM: 1.0 Introduction: The Stable Tropics Aren't So Stable When we think about the climate of the tropics, we tend...

The Atlantic’s Slowing “Heartbeat”: How a Fading Ocean Current Is Silencing a Major Climate Pattern

This blog post and the “Debate” podcast on a paper “Atlantic Meridional Overturning Circulation slowdown suppresses Atlantic Niño variability” by Freire-SouzaLi et al. (2025) was created by NotebookLM. Debate Podcast: This is different from Deep Dive Podcast. This is a debate between two hosts, illuminating different perspectives on the study, “Meltwater or Warming Drives Atlantic... 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 →

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...

Onset of 2025 Atlantic Niña: What it means for the Atlantic hurricane season (updated)

Atlantic Niña is a natural climate pattern characterized by cooler-than-average sea surface temperatures in the eastern equatorial Atlantic Ocean. It’s considered the 'cold phase' of what oceanographers call the Atlantic Zonal Mode, similar to how La Niña is the cold phase of the El Niño-Southern Oscillation (ENSO) in the Pacific. Looking at the latest NOAA... Continue Reading →

Storm-resolving climate models project a 36% increase in the year-to-year variability of Atlantic hurricane activity by the 2050s

Tropical cyclone (TC) activity results in substantial loss of life and property damage. While the Atlantic basin has experienced a pronounced increase in accumulated cyclone energy (ACE) and the number of TCs over the past 50 years, TC-resolving climate models project a slight decrease in TC frequency throughout the 21st century (e.g., Roberts et al.,...

Increasing ocean stratification intensifies sea surface temperature variability

As the surface ocean warms and polar ice sheets melt due to increasing anthropogenic greenhouse gases in the atmosphere, near-surface ocean stratification is increasing almost everywhere. In tropical and subtropical oceans, in particular, enhanced near-surface stratification inhibits the mixing between warmer surface water and cooler subsurface water, leading to a shallower surface mixed layer. In... Continue Reading →
