Quantifying historical trends in tropical cyclone activity has proved difficult, but a new reconstruction reveals clear global decline over the past century, driven by an increasingly cyclone-hostile environment troposphere.

This is the first year of a new grant. As such, I will briefly re-state the long-term goals. I am continuing research from my previous ONR grant on estimating the theoretical limits to tropical cyclone track errors, but with an emphasis now on distinguishing between overall track errors, and position and timing errors at landfall. My previous ONR grant showed a potential further halving of the ...

This paper aims to discuss the Seroja Tropical Cyclone and its impact on extreme weather. tropical cyclones occur from April 4 5th 2021, in East Nusa Tenggara (NTT) region. Based data Meteorology, Climatology Geophysics Agency (BMKG), initial position of cyclone was Savu Sea, southwest Timor Island. Since 1, NTT region has become center low pressure that triggers formation this cyclone. When a ...

Cyclone Yasi, one of the most severe tropical storms on record, crossed the central Great Barrier Reef (GBR) in February 2011, bringing wind speeds of up to 285 km hr⁻¹ and wave heights of at least 10 m, and causing massive destruction to exposed reefs in the Palm Island Group. Following the cyclone, mean (± S.E.) hard coral cover ranged from just 2.1 (0.2) % to 5.3 (0.4) % on exposed reefs and...

Ecological degradation within areas of remnant forest may be amplified if the effects of fragmentation interact with the effects of other environmental disturbances such as wind storms. We used before-after comparisons to assess the effects of Tropical Cyclone Larry on remnant and continuous rainforest in the Wet Tropics uplands of north-eastern Australia. Vegetation structure was measured thre...

The Third International Workshop on High-Resolution and Cloud Modeling: Tropical Cyclones and Climate was held at the University of Hawai‘i at Mānoa from December 2 to 4, 2008. The workshop assessed the current status of highresolution atmospheric models, with a focus on the simulation of tropical cyclones and the connection of tropical cyclones to climate variability and change. Key issues con...
