Ablation and Heat Exchange over the Khumbu Glacier

Quantifying ice cliff evolution with multi-temporal point clouds on the debris-covered Khumbu Glacier, Nepal

Measurements of glacier ice cliff evolution are sparse, but where they do exist, they indicate that such areas of exposed ice contribute a disproportionate amount of melt to the glacier ablation budget. We used Structure from Motion photogrammetry with Multi-View Stereo to derive 3-D point clouds for nine ice cliffs on Khumbu Glacier, Nepal (in November 2015, May 2016 and October 2016). By diff...

On the Vertical Exchange of Heat, Mass, and Momentum Over Complex, Mountainous Terrain

The role of the atmospheric boundary layer (ABL) in the atmosphere-climate system is the exchange of heat, mass, and momentum between “the earth’s surface” and the atmosphere. Traditionally, it is understood that turbulent transport is responsible for this exchange and hence the understanding and physical description of the turbulence structure of the boundary layer is key to assess the effecti...

Thermal windows and heat exchange

Endothermic animals, such as birds and mammals, regulate their body temperature balancing the amount of heat metabolically produced and that exchanged with the environment. Thus, whenever ambient temperature rises and/or metabolic heat production increases (such as during exercise), adjustments to promote heat dissipation are activated to defend body temperature. One of such adjustments modulat...

The nature of Over the Counter market and its distinction from Stock Exchange in Iran and the US Legal systems

Although clause 8 of article 1 of the Securities Market Act has been explained Over the Counter market and defined it to ”an electronic or non-electronic market which implements securities transactions on the basis of negotiations”, according to some changes in the rules and regulations of this section, including approval of Iranian Securities Market Act, The law for Development of New Financia...
