Background Error Covariance Matrix Structure and Impact in a Regional Tropical Cyclone Forecasting System

Remote Sensing
The background error covariance matrix (BE) is a fundamental component of data assimilation (DA) systems. Its impact on both the DA process and subsequent forecast performance depends on model configuration and the types of observations assimilated ...

An analysis of long-term relationships among count statistics and metrics of synthetic tropical cyclones downscaled from CMIP5 models [PDF]

, 2015
In a changing climate, the impact of tropical cyclones on the United States Atlantic and Gulf Coasts will be affected both by how intense and how frequent these storms become.

Improving Typhoon Predictions by Integrating Data‐Driven Machine Learning Model With Physics Model Based on the Spectral Nudging and Data Assimilation

Earth and Space Science
The rapid advancement of data‐driven machine learning (ML) models has improved typhoon track forecasts, but challenges remain, such as underestimating typhoon intensity and lacking interpretability. This study introduces an ML‐driven hybrid typhoon model,

Interactions Between a Marine Heatwave and Tropical Cyclone Amphan in the Bay of Bengal in 2020

Frontiers in Climate, 2022
Interactions are diagnosed between a marine heatwave (MHW) event and tropical super cyclone Amphan in the Bay of Bengal. In May 2020, an MHW developed in the Bay of Bengal driven by coupled ocean-atmosphere processes which included shoaling of the mixed ...

Investigating changes in global tropical cyclone storm frequency and intensity [PDF]

, 2010
Understanding fluctuations in tropical cyclone activity along United States shores and abroad becomes increasingly important as coastal managers and planners seek to save lives, mitigate damage, and plan for resilience in the face of changing storminess

Impact of large-scale dynamic versus thermodynamic climate conditions on contrasting tropical cyclone genesis frequency [PDF]

, 2017
Significant advances have been made in understanding the key climate factors responsible for tropical cyclone (TC) activity, yet any theory that estimates likelihood of observed TC formation rates from mean climate states remains elusive.

Predictability associated with extratropical transition of tropical cyclones as defined by operational ensemble prediction systems [PDF]

, 2004
The poleward movement of a decaying tropical cyclone often results in a rapidly-moving, explosively-deepening midlatitude cyclone. The re-intensification of the remnant tropical cyclone as an extratropical cyclone depends on the phasing between the ...

Physically-based landfalling tropical cyclone scenarios in support of risk assessment

Weather and Climate Extremes, 2019
Populations and property values are increasing in tropical cyclone prone regions, driving up repair and replacement costs following a tropical cyclone impact. Climate change influences on tropical cyclones and sea levels will only exacerbate these rises.

The relationship of western Pacific monsoon and tropical cyclone activity to North Pacific and North American climate anomalies [PDF]

, 1992
This present study investigates the influence of western Pacific tropical cyclone activity as possible centers of anomalous tropical heating on the large-scale circulation over the Pacific region.
