CONFERENCE-ARTICLE 6 Reads 0 Citations Synoptic climatology of cut-off low events that produced extreme precipitation in Valencia, Spain Rosana Nieto Ferreira Published: 08 November 2017

A seasonal synoptic climatology of cut-off lows (COLs) that produced extreme precipitation in the Valencia region of Spain during 1998-2014 is presented. COLs were shown to be the main producer of extreme precipitation in the region, especially during the transition seasons. The strongest raining COL events occurred during September-November. Six-day composites of lower and upper tropospheric winds, geopotential, sea-level pressure and precipitation show that COLs that produce extreme rainfall in this region remain stationary over Spain for 2-3 days and produce rainfall over the Valencia region for at least two days. In the low levels these COLs are characterized by low pressure over the Mediterranean sea and winds with an easterly, onshore component. Another interesting aspect of the composites is that transition season COLs are characterized by the presence of a filament of moisture that extends from the tropical Atlantic to Spain suggesting a role for remote moisture transport to feed COL rainfall. Further analysis is needed to confirm this hypothesis.

Midlatitude cyclones that affected the Southeast (SE) United States between 1998 and 2010 were classified into five types according to their region of origin: (1) Continental United States, (2) Canadian, (3) Gulf Low, (4) Hatteras Low, or (5) Stationary. A composite analysis was used to examine differences in the structure, evolution, and propagation of these cyclones during boreal winter, when the largest number of cyclones affect the SE United States. Most of the midlatitude cyclones that affect the SE in the wintertime formed within the continental United States (∼11 events/winter), followed by Gulf Lows (∼4 events/winter) and Canadian cyclones (∼4 events/winter). Hatteras Lows were relatively rare (∼1 events/winter), and Stationary events did not occur during winter. While Canadian and Continental US cyclones occurred year-round the frequency of Gulf Low events peaked in the boreal winter when the upper-level jet was strongest and located further south. Hatteras Lows peaked in the boreal fall and winter, and Stationary events occurred almost exclusively during the boreal summer. Overall, Gulf Low and Continental US cyclones were the only cyclones that brought wintertime precipitation to the SE United States. When integrated over the season, Continental US cyclones made the largest contribution to the wintertime precipitation in the SE United States. On a per-event basis, however, Gulf Lows were the biggest wintertime precipitation makers in the SE United States while Canadian cyclones and Hatteras Lows did not bring much precipitation to the SE United States. Gulf Lows were more common during El Niño than La Niña years and tended to occur back-to-back with either another Gulf Low or with a Hatteras Low.

A novel multinational course on global climate change was developed by East Carolina University in collaboration with five international universities and the U.S. Department of State. This course was developed to help foster the global conversation needed for developing successful solutions to some of the challenges posed to society by climate change. Using web conferencing technology, students from East Carolina University, Faculdade Jaguariúna in Brazil, Shadong University in China, University of Jammu in India, Universidad Regiomontana in Mexico, and Lomonosov Moscow State University in Russia met 2 or 3 times per week in the Global Classroom to learn about climate change science, mitigation and adaptation strategies, and domestic and international climate policy issues. In addition to learning about climate change, students worked in teams composed of members from each country to create locally implementable strategies for climate change mitigation and/or adaptation. Toward this end, students learned and were challenged to apply important cross-cultural negotiation and project building skills necessary to achieve consensus and ensure effective communication and team function. This article presents the course design, including content and the use of technology, as well as a discussion of the challenges and rewards associated with getting people from five countries together in a common pursuit of knowledge and consensus.

The impact of Amazon Basin convection and cold fronts on the formation and maintenance of the South Atlantic convergence zone (SACZ) is studied using aqua‐planet simulations with a general circulation model. In the model, a circular patch of warm sea‐surface temperature (SST) is used to mimic the effect of the Amazon Basin on South American monsoon convection. The aqua‐planet simulations were designed to study the effect of the strength and latitude of Amazon Basin convection on the formation of the SACZ. The simulations indicate that the strength of the SACZ increases as the Amazon convection intensifies and is moved away from the equator. Of the two controls studied here, the latitude of the Amazon convection exerts the strongest effect on the strength of the SACZ. An analysis of the synoptic‐scale variability in the simulations shows the importance of frontal systems in the formation of the aqua‐planet SACZ. Composite time series of frontal systems that occurred in the simulations show that a robust SACZ occurs when fronts penetrate into the subtropics and become stationary there as they cross eastward of the longitude of the Amazon Basin. Moisture convergence associated with these frontal systems produces rainfall not along the model SACZ region and along a large portion of the northern model Amazon Basin. Simulations in which the warm SST patch was too weak or too close to the equator did not produce frontal systems that extended into the tropics and became stationary, and did not form a SACZ. In the model, the SACZ forms as Amazon Basin convection strengthens and migrates far enough southward to allow frontal systems to penetrate into the tropics and stall over South America. This result is in agreement with observations that the SACZ tends to form after the onset of the monsoon season in the Amazon Basin. Copyright © 2012 Royal Meteorological Society
