Introduction: Generally, geometrical parameters of the cyclone have a profound effect on determining its performance. The air outlet (Vortex Finder) as one of the cyclone’s components has a significant impact on the cyclone’s internal flow pattern, pressure drop and even dust removal efficiency. Material and Methods: Two different air outlets were designed in order to be easily installed and r...

We consider a spatial stochastic model for the simulation of tropical cyclone tracks, which has recently been introduced. Cyclone tracks are represented as labeled polygonal lines, which are described by the movement directions, translational speeds, and wind speeds of the cyclones in regular six-hour intervals. In the present paper, we compare return levels for wind speeds of historically obse...

Tropical cyclone rainfall rates have been projected to increase in a warmer climate. The area coverage of tropical cyclones influences their impact on human lives, yet little is known about how tropical cyclone rainfall area will change in the future. Here, using satellite data and global atmospheric model simulations, we show that tropical cyclone rainfall area is controlled primarily by its e...

True random number generators (TRNGs) are fundamental constituents of secure embedded cryptographic systems. In this paper, we introduce a general methodology for porting TRNG across different FPGA vendor families. In order to demonstrate our methodology, we applied it to the delay-chain based TRNG (DC-TRNG) on Intel Cyclone IV and Cyclone V FPGAs. We examine vendor-agnostic generality of the u...

Contributions of biologists to tropical cyclone research may improve by integrating concepts from other disciplines. Employing accumulated cyclone energy into protocols may foster greater integration of ecology and meteorology research. Considering experienced ecosystems as antifragile instead of just resilient may improve cross-referencing among ecological and social scientists. Quantifying ec...

Over the global tropics, the Madden-Julian Oscillation (Madden and Julian 1994, MJO) explains a significant amount of the variability in circulation and convection on intraseasonal time scales. However, significant variation exists in the spatial extent and seasonal occurrence of the MJO. While the upper-level divergent flow associated with MJO is often traced around the globe, the low-level wi...

gonu storm was formed in tropical basin of indian ocean early in june 2007. gonu is the strongest tropical cyclone that happened in arabian sea and north indian ocean and moved toward oman sea and persian gulf and bouncing the lands around the area. this tropical cyclone made extensive damages and human and financial causalities to countries of oman, iran, afghanistan, pakistan, and india. in t...

A new multi inner stage (MIS) cyclone was designed to remove the acidic gas and fine particles produced from electronic industry. To characterize gas flow in MIS cyclone, pressure and velocity distribution were calculated by means of CFD program. Also, the flow locus of fine particles and particle removal efficiency were analyzed by Lagrangian method. When outlet pressure condition was –100mmAq...

A long-term goal of this research is to improve dynamical prediction of tropical cyclones using ensemble methods for making analyses and forecasts. A second goal is to use the information contained in ensemble analyses and forecasts to improve basic understanding of tropical cyclone dynamics. Finally, a third goal is to use ensemble-based sensitivity analysis to target observations for tropical...
