34 st / February 2017 Arabian/Persian Gulf, a unique weather phenomenon occurs throughout the year and has substantial impact on the soci- ety, economy, transportation, and the natural environment; it is known as a Shamal event." Anis, a physical oceanographer and professor in the department of marine sciences at Texas A&M University, Galveston, and in the department of oceanography at Texas A&M University, College Station, continues to conduct stud- ies to examine Shamal events and their effect on the hydro- dynamics and water properties in the northern Arabian Gulf. Anis's recent research set out to examine the response of the water column to Shamal events. Various meteorologi- cal data were collected over two periods—mid-January to mid-April 2013 and mid-October to mid-January 2014—and S hamals are strong, dry winds blowing from the North- Northwest that have a significant impact on surface heat (shortwave, longwave, sensible and latent) and momentum fluxes. Dr. Ayal Anis and Dr. Fahad Al Senafi broadly de- scribe Shamal in a previous paper based on a 40-year study and explain the importance of research in understanding the impact of global climate change: "Effects of global climate change on the relative increase of surface temperatures, droughts, flooding, and intensity of weather events such as monsoons and hurricanes have been increasing steadily. The rise in number of environmental catastrophes due to severe weather events in the last 50 years has further mo- tivated scientists to better understand the impacts of global climate change on weather systems and phenomena. In the Data Loggers for Environmental Research miniDOT, Cyclops-7 Loggers Monitor Water Response to Weather By Kristin Elliott Surface meteorological and hydrographical observations in the northern Arabian Gulf, January to February 2013. Two Shamal events occurred during this period. (A) Surface wind stress, (B) net surface heat flux, (C) light intensity, (D) temperature and (E) dissolved oxygen. (Image Credit: Dr. Ayal Anis)
