Vertical profiles of carbon monoxide (CO) and ozone retrieved from Tropospheric Emission Spectrometer have been analyzed during two super cyclone systems Mala and Sidr. Super cyclones Mala and Sidr traversed the Bay of Bengal (BOB) region on April 24-29, 2006 and November 12-16, 2007 respectively. The CO and ozone plume is observed as a strong enhancement of these pollutants in the upper tropos...

This paper explores the potential of construction process simulation as a web service. This web service, or web based application, exploits the high accessibility characteristic of the web, to support easier information exchange and peer collaboration. Two concepts are discussed and presented. One web based prototype called “Interactive Simulation System (ISS)” allows a user unfamiliar with sim...

The Madden-Julian oscillation (MJO) has been documented in previous studies to significantly impact tropical cyclone activity in all ocean basins. Most of these studies have utilized the Wheeler-Hendon index. This index is only available since 1974, the period over which remotely sensed outgoing longwave radiation data has been available. Our study utilizes a long reconstructed MJO index, based...

[1] Recent historical Northern Hemisphere (NH) tropical cyclone (TC) inactivity is compared with strikingly large observed variability during the past three decades. Yearly totals of the combined active-basin NH accumulated cyclone energy (ACE) are highly correlated with boreal spring seasurface temperature (SST) in the North Pacific Ocean and are representative of an evolving dual-gyre, trans-...

The large-scale equatorial circulation known as the Madden–Julian oscillation (MJO) has been shown to impact tropical cyclone activity in several basins around the globe. In this paper, the author utilizes an MJO index created by Wheeler and Hendon to examine its impacts on tropical genesis and intensification in the Atlantic. Large differences in frequency and intensity of tropical cyclone act...

[1] A coupled biophysical model is used to examine the impact of the great Arctic cyclone of early August 2012 on the marine planktonic ecosystem in the Pacific sector of the Arctic Ocean (PSA). Model results indicate that the cyclone influences the marine planktonic ecosystem by enhancing productivity on the shelves of the Chukchi, East Siberian, and Laptev seas during the storm. Although the ...

A Response surface design of experiment has been performed based on the Muschelknautz method of modeling (MM) for 64 test cases using Box-Behnken design to study the effect of seven geometrical cyclone dimensions on the pressure drop and cut-off diameter. It is found that the most significant geometrical parameters are, the vortex finder diameter, the inlet section width and height, and the cyc...

Future climate projections show higher/lower winter (Dec-Jan-Feb) precipitation in the northern/southern Mediterranean region than in present climate conditions. This paper analyzes the results of regional model simulations of the A2 and B2 scenarios, which confirm this opposite precipitation change and link it to the change of cyclone activity. The increase of the winter cyclone activity in fu...

The issue of the relationship between the central mean sealevel pressure (Pc) and maximum mean near-surface wind* (the wind-pressure relationship, hereafter WPR) in a tropical cyclone (TC) has been the subject of ongoing debate for many decades and a number of relationships have been developed during this period. This is demonstrated by the fact that the three Australian Tropical Cyclone Warnin...

Modern computer graphics systems are able to render sophisticated 3D scenes consisting of millions of polygons. For most camera positions only a small collection of these polygons is visible. We address the problem of occlusion culling, i.e., determine hidden primitives. Aila, Miettinen, and Nordlund suggested to implement a FIFO buffer on graphics cards which is able to delay the polygons befo...
