What are the differences between the convection and conduction currents? What causes wind to blow? Describe the cause andeffects of air movements and ocean currents How are AC currents produced? What is the basic principle behind convection?
We present results from a laboratory study that demonstrate how shear and convection in the ice–ocean boundary layer can lead to significant gas exchange. In the absence of wind, water currents beneath the ice of 0.23 m s −1 produced a gas transfer velocity ( k ) of 2.8 m d −1 ...
The development of a storm-generated pressure field must be called upon to increase the magnitude of the density and basic currents to more than 30 m/s. Such conditions occur only when the convection is embedded in squall lines which reach their diurnal maximum at locations nearly coincident ...
Our page top photo, courtesy ofIndoor Air Care, shows water inside of flexible ductwork. Are these due to roof leaks, condensate leaks into the duct system from the air handler, or condensate due to convection air currents entering the HVAC duct during the heating season? In freezing climates...
Convection currents and gravitational forces move tectonic plates. The contact between plates, creates earthquakes, volcanoes, islands and mid ocean ridges. Mountain ranges, are examples of converging plates and modern technology can help scientists locate tumours or movement in the Earth.-Thesis-...
Oceanic tides lead to some of the largest currents of the world ocean and have important implications for oceanic circulation. In the last decade, the feedback effect of surface currents on the overlying winds has been shown to strongly regulate the ocean circulation. Here we present evidence, ...
But the friend who demands more of you than you want to give – treat him/her with kid gloves. The vulnerable can’t always handle, ‘no’. Take time to give them a break and understand their needs. Being there for others does us the most good. ...
These evolutions in the field, which happen on a similar time scale to the convection of metals in the outer core, provide scientists with new clues to help them unravel the core dynamics that drive the geodynamo. “The magnetic field is actually a superposition of fields f...

Excessive air convection in the chamber was avoided by using additional plastic curtains placed inside the chamber. The relative effective resistivity increase (γ) was calculated based on the effective resistivity at a RH of 0% and at a given RH of x%. γ = ρERFHF=x% ρERFHF=0% −...
