They are the minimum atomospheric pressure, maximum wind velocity near typhoon center, move speed of typhoon center, the radius of typhoon, the shortest distance between typhoon center and Taipei monitoring station, station humidity.本研究先选取影响台风雨之因子,选用钟型函将中心最低气压、近中心最大...
Fortunately , of the winds coming from all directions toward the Mogao Grottoes , only the southwester with a probability of 5.6% has a velocity of over 8 m /s. 值得庆幸的是,在莫高窟的八面来风中,只有概率占5.6%的西南风达到每秒8米以上的等级。 台风typhoon But after the typhoon , the islan...
The wind energy resources can be quantitatively measured by the wind power density (WPD), which is defined as the mean annual power available per square meter of the swept area of a wind turbine in different heights above the ground. WPD is calculated based on the wind velocity and the air...
WPD- Instantaneous Wind Power Density. Measure of power available in the wind: ½ρv3, where ρ is air density and v is wind velocity TPW- Total Precipitable Water. Total amount of water in a column of air stretching from ground to space ...
Seed traits such as terminal velocity (that is, seed falling velocity in still air) or buoyancy are often used to assess whether species are potentially capable of long-distance dispersal via wind or water (Ozinga and others 2009; Thomson and others 2010). However, this results in rough ...
in Southern Europe and Asia (Fig.5a). Compared to Northern Europe, the largest deviations of environmental variables were found for Southern America and Africa, showing higher temperatures, lower Chlaconcentrations, lower NO3-concentrations, and higher flow velocities (Fig.5b–e). Flow velocity is ...
7. ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) defines “still air” as when the velocity of air is below 0.15m/s, so people cannot feel any cold drafts. Simply smart Wi-Fi Control with SmartThings app ...
The corresponding averaged bulk velocity is 4.47 m/s (uref) and the average mass flow rate through the channel is 0.262 kg/s per unit area [17], [18]. 3. Computational set-up 3.1. Computational domain and grid A computational domain of the cube (H = 0.015 m) including the epoxy ...
