This paper describes the influence of atmospheric conditions on performance a vehicle. Tests were carried out road, under different ambient temperature, pressure and humidity, measuring acceleration time. The tested vehicle featured gasoline-fuelled four-cylinder engine, with variable intake manifold length multipoint fuel injection. was at sea level an altitude 827 m above level, temperature ranging from 20 to 30°C. times required for go 80 120 km/h, 40 100 km/h reach distances 400 1000...
Abstract We investigate the characteristics of shear‐generated turbulence in natural environment by considering data from a number cruises western equatorial Pacific. In this region, vertical shear flow is dominated structures that have relatively small scale O(10 m). Combining all cruises, we find strong relationship between turbulent dissipation rate, ϵ , shear, S and buoyancy frequency, N . Examination at fixed value Richardson number, Ri = 2 ∕ shows for wide range values where u t an...
Abstract A developing MJO event in the tropical Indian Ocean triggered wind disturbances that generated inertial oscillations surface mixed layer. Subsequent radiation of near‐inertial waves below layer produced strong turbulence pycnocline. Linear plane wave dynamics and spectral analysis are used to explain these observations, with ultimate goal estimating energy flux relation both input by dissipation turbulence. The results indicate packets carry approximately 30–40% kinetic energy,...
This work evaluates proposed methods to correct engine power output as a function of atmospheric conditions. The analysis was made through experiments carried out in vehicle on the road, under different temperature, pressure and air humidity had four-cylinder gasoline-fuelled engine, with multi-point fuel injection system, variable intake pipe length valve camshaft position. tested at sea level 827 m above level, corresponding pressures between 1027 926 mbar. Air temperature varied from 22,8...
Easterly waves (EW) are low level tropical atmospheric disturbances able to resonantly force strong mixed layer inertial currents. Using data from two Tropical Atmosphere Ocean/Eastern Pacific Investigation of Climate Processes (TAO/EPIC) buoys located along 95°W and a multiparameterization one‐dimensional turbulence model, we examine how the EW‐forced surface kinetic energy (IKE) loss is partitioned between turbulent dissipation near‐inertial wave (NIW) radiation. Several EW‐forcing events...
Abstract Scale interactions in the coupled ocean and atmosphere of tropics play a crucial role shaping climate state its spatial temporal variability. The mechanisms driving seasonal cycles mixed layer (ML) temperature salinity tropical south Indian Ocean (TSIO) are revisited quantified using model observations to form basis on which assess cycle’s impact shorter longer time scale variability region. Budgets ML heat for western, central, eastern TSIO both indicate that seasonality is driven...
Abstract Kinetic energy associated with inertia–gravity waves (IGWs) and other ageostrophic phenomena often overwhelms kinetic due to geostrophic motions for wavelengths on the order of tens kilometers. Understanding dependencies wavelength at which balanced (geostrophic) variability ceases be larger than unbalanced is important interpreting high-resolution altimetric data. This has been termed transition scale. study uses acoustic Doppler current profiler (ADCP) data along auxiliary...
