Multi-cyclone analysis and machine learning model implications of cyclone effects on forests

چکیده
Past studies of cyclones (hurricanes, typhoons, tropical cyclones) disturbance showed that meteorological, topographical, and biological factors affect the patterns forest intensity but left open extent to which these findings were representative across different global cyclone regions. Using remote sensing data machine learning models, we examined how change over spatial scales assessed their consistency four major cyclones: Katrina (August 2005), Rita (September Yasi (February 2011), María 2017). Our results revealed best explained pattern varied Wind speed precipitation dominant contributing variation in impacts Katrina; terrain features, especially elevation, most Rita; pre-disturbance vegetation condition was significant predictors effects Yasi; played equal roles explaining María. A 40 m/s (144 km/h) wind threshold proposed split low- high-level intensity. Other than speed, few generalizations can be made on features multiple We built several generalized hurricane impact worked well with test from used for model development (R2 = 0.89). However, models did not have good predictions other cyclones, such as Michael (October 2018) Laura 2020). This study each interacted landscape a unique way challenges remained building model.

Particle Size Effects on Hydro-Cyclone Performance
The hydrocyclone has a very important roll in industrial separation. The consideration of its behavior is very important for design. In this investigation, behavior of water flow and particles trajectory inside a hydrocyclone has been considered by means of numerical and experimental methods, and results have been compared together. To have a numerical simulation, a CFD software was used, and f...
متن کاملDynamics and Thermodynamics Analysis of Tropical Cyclone Haiyan
Tropical cyclone Haiyan (TCH) that formed over the West Pacific Ocean during 3-11 November 2013 has been investigated using three datasets produced by Japan Meteorology Agency, ECMWF and NCEP. Strength of TCH has been studied using two synoptic parameters of 10-m wind velocity and mean sea level pressure (MSLP). Following, three dynamic parameters including vertical wind shear (VWSH) vector, he...
متن کاملStatistical modelling of tropical cyclone tracks: modelling cyclone lysis
We describe results from the fifth stage of a project to build a statistical model of tropical cyclone tracks. The previous stages considered genesis and the shape of tracks. We now consider in more detail how to represent the lysis (death) of tropical cyclones. Improving the lysis model turns out to bring a significant improvement to the track model overall.
متن کاملA mathematical model of the nascent cyclone
In this letter, we have proposed a mathematical modeling of a disturbance created by winds coming from different directions and colliding to give rise to a vortex under certain conditions. Under favorable conditions, this vortex may lead to the development of a cyclonic storm (cyclogenesis).

This paper tends to investigate the performance of a separator cyclone used in cement industries in Iran. This investigation was performed using CFD modeling, which is validated by other valid studies. Separator cyclone performance includes of two important parameters as pressure drop and collection ratio. In this presented study, the pressure drop has been considered to assess the performance ...
