Tropical cyclones provide an important source of ocean mixing, bringing cold, nutrient‐rich water to the surface and triggering phytoplankton blooms. Here, we show significant increases in global tropical cyclone‐induced sea surface temperature cooling and surface chlorophyll‐a concentration of 0.05°C and 3.7 × 10−3 mg m−3 per decade over the past 20–35 years. The trends have been driven primarily by an increase in the intensity of strong tropical cyclones. The increase in chlorophyll‐a… 

Decrease of Annually Accumulated Tropical Cyclone‐Induced Sea Surface Cooling and Diapycnal Mixing in Recent Decades

Tropical cyclones (TCs) are an important source of turbulent mixing for the upper ocean at low latitudes, causing sea surface cooling and subsurface warming. A new estimate of annually accumulated

Recent tropical cyclone changes inferred from ocean surface temperature cold wakes

This analysis provides new independent and indirect evidence of recent TC LMI increases, but a stable size and integrated kinetic energy.

Drivers of Phytoplankton Variability in and Near the Pearl River Estuary, South China Sea During Typhoon Hato (2017): A Numerical Study

The Pearl River Estuary and adjacent seas in South China Sea are frequently affected by tropical cyclones (TCs). Previous in situ and remote sensing studies have found that typhoons can enhance

Physical and Biochemical Responses to Sequential Tropical Cyclones in the Arabian Sea

The upper-ocean physical and biochemical responses to sequential tropical cyclones (TCs) Kyarr and Maha in the Arabian Sea (AS) were investigated using data from satellites and Bio-Argo floats.

Fragility of marine photosynthesis

Ecosystem fragility is an often used term in oceanography yet to this day it lacks a precise and widely accepted definition. Defining and subsequently quantifying fragility would be of great value,



Global impact of tropical cyclones on primary production

In this paper, we explore the global responses of surface temperature, chlorophyll, and primary production to tropical cyclones (TCs). Those ocean responses are first characterized from the

New evidence for enhanced ocean primary production triggered by tropical cyclone

New evidence based on recent satellite data is presented to provide a rare opportunity in quantifying the long‐speculated contribution of tropical cyclones to enhance ocean primary production. In

A reassessment of the integrated impact of tropical cyclones on surface chlorophyll in the western subtropical North Atlantic

The impact of tropical cyclones on surface chlorophyll concentration is assessed in the western subtropical North Atlantic Ocean during 1998–2011. Previous studies in this area focused on individual

Changes in Tropical Cyclone Number, Duration, and Intensity in a Warming Environment

A large increase was seen in the number and proportion of hurricanes reaching categories 4 and 5 and the number of cyclones and cyclone days has decreased in all basins except the North Atlantic during the past decade.

Observation-Based Estimates of Surface Cooling Inhibition by Heavy Rainfall under Tropical Cyclones

Tropical cyclones drive intense ocean vertical mixing that explains most of the surface cooling observed in their wake (the “cold wake”). In this paper, the authors investigate the influence of

A global slowdown of tropical-cyclone translation speed

The translation speed of tropical cyclones has decreased globally by 10% over the past 70 years, which is very likely to have compounded, and possibly dominated, any increases in local rainfall totals that may have occurred as a result of increased tropical-cyclone rain rates.

Dynamic Potential Intensity: An improved representation of the ocean's impact on tropical cyclones

To incorporate the effects of tropical cyclone (TC)‐induced upper ocean mixing and sea surface temperature (SST) cooling on TC intensification, a vertical average of temperature down to a fixed depth

The increasing intensity of the strongest tropical cyclones

The results are qualitatively consistent with the hypothesis that as the seas warm, the ocean has more energy to convert to tropical cyclone wind.

Rainfall-enhanced blooming in typhoon wakes

It is suggested that rainfall plays a previously unrecognized, critical role in TC-induced blooming, with potentially important implications for global biogeochemical cycles especially in view of the recent and projected increases inTC-intensity that harbingers stronger mixing and heavier rain under the storm.

Northwestern Pacific typhoon intensity controlled by changes in ocean temperatures

An anomalously strong LLNWP upper ocean warming has favored increased intensification rates and led to unprecedentedly high average typhoon intensity during the recent global warming hiatus period, despite a reduction in intensification duration tied to the central equatorial Pacific surface cooling.
