[1] Long-term climate trends of surface air temperature should not be expected to have the same trends for light wind and stronger wind nights, even if the trends in the boundary layer heat fluxes were the same. Parker (2004) segmented observed surface temperature data into lighter and stronger wind terciles in order to assess whether the reported large-scale global-averaged temperature increas...

The wind blowing over sea surface generates tiny wind waves. They develop with time and space absorbing wind energy, and become huge wind waves usually referred to ocean surface waves. The wind waves cause not only serious sea disasters but also take important roles in the local and global climate changes by affecting the fluxes of momentum, heat and gases (e.g. CO2) through the air-sea boundar...

Just a few decades ago, almost all ocean wind measurements came from merchant ships. However, the quality and geographical distribution of these wind reports were uneven. The quality of historical wind-stress have been well investigated [e.g., Cardone et al., 1990; Trenberth, et al, 1990; Kent et al., 1999]. Today, operational numerical weather prediction (NWP) also gives us wind information, b...

Understanding some of the basic wind engineering concepts helps one understand the chimney’s response. The circular cross section of the steel chimney characteristically provides aerodynamic lift perpendicular to the wind direction. Knowing how to predict and prevent these adverse responses is of critical importance to steel chimney design. I. STATIC WIND FORCES The force exerted by wind varies...

Indian Ocean is known as a source of moisture for southeast of Iran due to summer precipitation. In this study, in order to investigate the role of SST of Indian Ocean, and the convergence and divergence fields in the precipitation of southeast of Iran, precipitation data of five synoptic stations were used during 2000-2010, including Iranshahr, Khash, ChahBahar, Zabul, and Saravan. To investig...

surface ozone (surface o3)is a secondary pollutant and there are only limited studies on ozone in south india. studies have revealed a strong correlation between higher ozone levels and warmer days. surface o3 along with its precursors like no2, co and ch4 are being measured at kanyakumari (8.0780° n, 77.5410° e), tamilnadu, india and in this paper we present the summer time variation of ozone ...

Applying corona wind as a novel technique can lead to a great level of heat and mass transfer augmentation by using a very small amount of energy. The enhancement of forced flow evaporation rate by applying electric field (corona wind) has been experimentally evaluated in this study. Corona wind produced by a fine wire electrode charged with positive high DC voltage impinges on water surface an...

Tropical cyclones (TC) transfer kinetic energy to the upper ocean and thus accelerate mixed layer (OML) currents. However, quantitative link between near-surface currents high wind speeds, under extreme weather conditions, remains poorly understood. In this study, we use multi-mission satellites drifting-buoy observations investigate connections TC surface winds currents, including their spatia...
