Journal of Operational Meteorology Short Contribution Dual-Polarization Radar Analysis of Northwestern Nevada Flash Flooding and Haboob: 10 June 2013 DAVID T. MYRICK NOAA/National Weather Service, Reno, Nevada JEREMY R. MICHAEL NOAA/National Weather Service, Elko, Nevada (Manuscript received 29 October 2013; review completed 8 January 2014) ABSTRACT A slow-moving complex of thunderstorms formed across northwestern Nevada on 10 June 2013 in the deformation zone of an approaching upper-level low-pressure system. Storm redevelopment along outflow boundaries resulted in urban and rural flash flooding. On the eastern flank of the thunderstorm complex, strong outflow boundaries lofted dust to form a large haboob. The haboob propagated eastward across north- central Nevada and resulted in a 27-car pileup on Interstate 80 near Winnemucca. Three examples are presented that demonstrate how dual-polarization radar technology aided forecasters in (i) discriminating heavy rain from hail and (ii) tracking the haboob. 1.

  • Sand and Dust Storms: Acute Exposure and Threats to Respiratory Health
    American Thoracic Society PATIENT EDUCATION | RAPID RESPONSE SERIES Sand and Dust Storms: Acute Exposure and Threats to Respiratory Health Sand and dust storms are lower atmosphere events that occur when strong winds pass over dry loose sand or soil. Sand and dust storms, also known as a haboob (Arabic for strong wind) are caused by airborne organic and inorganic debris, ranging from large sand particles to small dust particles, lifted from the surface of the land. This phenomenon excludes other sources of dust such as indoor environmental dust, cosmic dust, volcanic dust and smoke particles. Sand and dust storms can cause respiratory problems for people who are exposed, particularly those who have lung disease. As an example, in early July 2018, Arizona experienced strong winds resulting in the first big dust storm of the 2018 monsoon season. Dust storm.

  • Naming of Tropical Cyclones Over the North Indian Ocean Cyclone Warning Division India Meteorological Department
    Naming of Tropical Cyclones over the North Indian Ocean Cyclone Warning Division India Meteorological Department 1. Historical Background: The practice of naming storms (tropical cyclones) began years ago in order to help in quick identification of storms in warning messages because names are presumed to be far easier to remember than the numbers and technical terms. Many agree that appending names to storms makes it easier for the media to report on tropical cyclones, heightens interest in warnings and increases community preparedness. Experience shows that the use of short, distinctive names in written as well as spoken communications is quicker. In the beginning, storms were named arbitrarily. Then the mid-1900's saw the start of the practice of using feminine names for storms. In the pursuit of a more organized and efficient naming system, meteorologists later decided to identify storms using names from a list arranged alphabetically. Thus, a storm with a name which begins with A, like Anne, would be the first storm to occur in the year. Before the end of 1900's, forecasters started using male names for those forming in the Southern Hemisphere. Since 1953, Atlantic tropical storms have been named from lists originated by the National Hurricane Center. They are now maintained and updated by an international committee of the World Meteorological Organization. It is important to note that tropical cyclones /hurricanes are named neither after any particular person, nor with any preference in alphabetical sequence. The tropical cyclone/hurricane names selected are those that are familiar to the people in each region. Obviously, the main purpose of naming a tropical cyclone/hurricane is basically for people to easily understand and remember the tropical cyclone/hurricane in a region, thus to facilitate tropical cyclone/hurricane disaster risk awareness, preparedness, management and reduction.

  • Lassoing the Haboob Countering Jama’At Nasr Al-Islam­ Wal Muslimin in Mali, Part II
    DIGITAL - ONLY FEATURE Lassoing the Haboob Countering Jama’at Nasr al-Islam wal Muslimin in Mali, Part II MAJ RYAN CK HESS, USAF he preceding article argued that Jama’at Nasr al- Islam wal Muslimin ( JNIM) activity in Mali and the greater Sahel, coupled with the group’s integration into society, represents an existential threat to Mali. It illus- Ttrated how the gradual degradation of the Malian state is advantageous to JNIM and fits into its narrative of state weakness and lack of governance. As state power declines in Mali, the possibility of the government’s efforts to thwart JNIM similarly devolving into something resembling Afghanistan increases precipi- tously. The objective of the first article was an increased understanding of the root causes of Mali’s current instability and the characteristics of its most dangerous extremist group. Armed with such understanding, one can begin to develop strat- egies that work toward the goals of simultaneously combating JNIM and improv- ing Malian stability and governance—thereby avoiding a fate similar to that of Afghanistan. Providing and explaining strategies with those objectives is the main thrust of this article. This piece provides two strategic recommendations, both of which are inspired by lessons learned from US and international actions in Afghanistan. I argue that by developing policy based on the successes and failures of international efforts in the Middle East and South Asia, the international community might be able to ensure that the situation in Mali does not follow a similar path. The first strategy, defense institution building (DIB), is intended to reform and revitalize the Malian security apparatus so that it can be independently respon- sible for the protection of Malian citizens and interests.

  • “Monsoon” Refers to the Wind Shift That Brings Us Thunderstorms During the Summer Months of Late June, July, August and Early September
    The Arizona Monsoon Reading The term “monsoon” refers to the wind shift that brings us thunderstorms during the summer months of late June, July, August and early September. During the winter, the wind flow is from the west (California) or the northwest (Nevada). When summer comes, the winds come from a southern (Mexico and Gulf of California) or southeastern direction (Gulf of Mexico). This change in wind direction allows summertime moisture to move from the Pacific Ocean and the Gulf of California into Arizona and provides fuel for thunderstorms. Wind Direction in the Summer http://www.wrh.noaa.gov/twc/monsoon/monsoon_NA.php Meteorologists (people who study the weather) say the causes of the monsoon are: • The movement of huge upper air high-pressure cells to the north as winter changes to summer • The heating (100o to 108oF in Phoenix) of the desert that creates rising air and surface low-pressure. The two charts below show the difference between the high-pressure cells in June and July. Look where the high (H) is in relation to Arizona. High Pressure Cell in June and July June July http://www.wrh.noaa.gov/twc/monsoon/monsoon_NA.php Because the high-pressure cell moves northward and the temperatures rise, thunderstorms often develop during the summer. The Arizona storms usually are quick and last about 30-40 minutes. These storms develop in stages. In the first stage, warm air rises and forms cumulus-type clouds. Next strong currents of air move up and down. When the air hits the ground, a dust storm (called a haboob) is created.
