Clouds within the inner regions of tropical cyclones are unlike those anywhere else in the atmosphere. Convective clouds contributing to cyclogenesis have rotational and deep intense updrafts but tend to have relatively weak downdrafts. Within the eyes of mature tropical cyclones, stratus clouds top a boundary layer capped by subsidence. An outward-sloping eyewall cloud is controlled by adjustm...
Episodic eddy-driven upwelling may supply a significant fraction of the nutrients required to sustain primary productivity of the subtropical ocean. New observations in the northwest Atlantic reveal that, although plankton blooms occur in both cyclones and mode-water eddies, the biological responses differ. Mode-water eddies can generate extraordinary diatom biomass and primary production at de...
The National Typhoon Center of the Korea Meteorological Administration developed a statistical–dynamical typhoon intensity prediction model for western North Pacific, CSTIPS-DAT, using track-pattern clustering technique. led to significant improvements in tropical cyclones (TCs). However, relatively large errors have been found cluster located Pacific (TWNP), mainly because predictand variance....
[1] The NASA Global Modeling and Assimilation Office (GMAO) has developed a global non‐hydrostatic cloud‐ system resolving capability within the NASA Goddard Earth Observing System global atmospheric model version 5 (GEOS‐5). Using a non‐hydrostatic finite‐volume dynamical core coupled with advances in the moist physics and convective parameterization the model has been used to perform cloud‐sy...
The wind speed forecasting in Hong Kong is more difficult than in other places in the same latitude for two reasons: the great affect from the urbanization of Hong Kong in the long term, and the very high wind speeds brought by the tropical cyclones. Therefore, prediction model with higher learning ability is in need for the wind speed forecast in Hong Kong. In this paper, we try to employ the ...
[1] In March 2004 the first-ever reported hurricane in the South Atlantic hit southern Brazil. Here we show that Catarina initiated as an extratropical cyclone in a frontal system, undergoing Tropical Transition two days later under persistent low vertical wind shear over near-average water temperatures. The trajectory derived from an automatic tracking scheme showed a rare loop before the cycl...
Abstract. Atmospheric fronts are a widely used conceptual model in meteorology, most encountered as two-dimensional (2-D) front lines on surface analysis charts. The three-dimensional (3-D) dynamical structure of has been studied the literature by means “standard” 2-D maps and cross-sections is commonly sketched 3-D illustrations idealized weather systems atmospheric science textbooks. However,...
Monitoring changes in coral cover and composition through space and time can provide insights to reef health and assist the focus of management and conservation efforts. We used a meta-analytical approach to assess coral cover data across latitudes 10-35°S along the west Australian coast, including 25 years of data from the Ningaloo region. Current estimates of coral cover ranged between 3 and ...
