Recent tropical cyclone changes inferred from ocean surface
2021年11月15日 · We find a globally enhanced local cold wake amplitude 3 days after the LMI of − 0.12 ± 0.04 °C per decade whereas the cold wake size does not show any significant change.
The Feedback of Cold Wakes on Tropical Cyclones
2021年4月9日 · Tropical cyclones (TCs) cause negative sea surface temperature anomalies by vertical mixing and other processes. Such cold wakes can cover substantial areas and persist for a month or longer. It has long been hypothesized that cold wakes left behind by intense TCs reduce the likelihood of subsequent TC development.
Strengthening cold wakes lead to decreasing trend of tropical cyclone ...
2023年9月5日 · Tropical cyclone (TC) rainfall is an important component of global precipitation. Based on a 22-year satellite-based record of observed precipitation from 1998 to 2019, we find that composite...
Long-lasting upper ocean temperature responses induced by …
2022年4月6日 · The sea surface temperature (SST) drops rapidly when a typhoon passes over the western North Pacific, and the cold SST is known as cold wake. In general, more intense typhoons on the day of...
Modulation of Clouds and Rainfall by Tropical Cyclone's Cold …
2020年8月21日 · Here we show that local clouds and rainfall are effectively modulated by cold wakes left behind by tropical cyclones using a combination of satellite observations. On average, the negative surface enthalpy flux anomaly associated with the cold wake results in a reduction of rainfall by ~16.6 ± 0.6% (standard error) and a decline of cloud ...
Footprint of Tropical Cyclone Cold Wakes on …
2021年9月21日 · The upper ocean stirred by tropical cyclones leaves a cold wake at the surface. Though the impact of cold wakes on ocean heat pumping, heat transport, and storm intensity were extensively explored for years, only recently have their modulation effects on rainfall and clouds been demonstrated.
Recent tropical cyclone changes inferred from ocean surface …
TCs impact the ocean surface temperature by creating cold wakes as a “fingerprint”. Here we infer changes of the lifetime maximum intensity (LMI), size and integrated kinetic energy from the cold wakes for the period 1982–2019.
Tropical cyclones (TCs) cause negative sea surface temperature anomalies by vertical mixing and other processes. Such cold wakes can cover substantial areas and persist for a month or longer. It has long been hypothesized that cold wakes left behind by intense TCs reduce the likelihood of subsequent TC development.
Quantifying the Rightward Bias Extent of Tropical Cyclones' Cold …
Mixing of the upper ocean by the wind field associated with tropical cyclones (TCs) creates observable cold wakes in sea surface temperature and may potentially influence ocean heat uptake.
Air-Sea Interactions in the Cold Wakes of Tropical Cyclones
2020年12月6日 · Tropical cyclones generate a large and wide cold wake along their trajectories, which conditions the subsequent evolution of the tropical cyclone themselves. The cold wakes persist for weeks, impacting both the upper ocean, the air-sea fluxes, and the atmosphere.
