We are a small team consisting of four University of Oklahoma graduate students, a CIMMS research associate, and are supervised by a research meteorologist, Michael Douglas, who works for the National Severe Storms Laboratory (NSSL), which is part of the National Oceanic and Atmospheric Administration (NOAA). We are based in Norman, Oklahoma, in the south-central Great Plains of the United States of America. All of us are working on some aspect of tropical and mesoscale meteorology/climatology. Our activities have concentrated on the tropical Americas where we have participated in numerous field campaigns and related research such as the South American Low Level Jet Experiment (SALLJEX), the North American Monsoon Experiment (NAME) and the Pan American Climate Studies Sounding Network (PACS-SONET). Most of the group's activities have been associated with developing and maintaining the PACS-SONET from early 1997 through 2006. The goal of this project was initially to determine the atmospheric circulations associated with wet and dry spells in Central America during the rainy season. As the project grew, the objectives were extended to motivate countries with small budgets for meteorological observations to carry out routine upper-air measurements using the relatively inexpensive technology of pilot balloons. The PACS-SONET has involved 13 countries in the Americas and has installed and operated a total of 66 pilot balloon stations (not all at once!), without counting special sites established for short field experiments carried out in Panama, Peru, Ecuador, Venezuela and Bolivia. Although this NAMMA web site describes activities geographically far from our Latin American activities, it applies a blend of simple and high technology approaches to address a fundamental problem in tropical meteorology - that of tropical cyclogenesis.

Our team consists of:

Michael Douglas
Ph.D. in Meteorology and NOAA research Meteorologist at NSSL
Mike carries out research in a variety of areas of mesoscale and tropical meteorology. His graduate work involved analysis of GATE and MONEX field experiment data, but then proceeded into high latitude winter storm studies with research aircraft. In 1990 he returned to tropical research topics.

Javier Murillo
B.Sc. in Electrical Engineering and Research Assistant at CIMMS
Javier, originally from Mexico, has been working with us since late 1999. Javier worked for many years in the Mexican Weather Service. Javier has been overseeing the daily logistics, communications and overall coordination of the PACS-SONET activities.

John Freddy Mejía
M.Sc. in Hydrology and Graduate Research Assistant
Freddy is from Medellin, Colombia. He has a degree in Civil Engineering and a M.S. in Hydrological Resources. Freddy is pursuing a PhD in Meteorology at OU. He, as the rest, has participated in all of the projects and at the moment is focusing on the NAME project and has an active role in the office. Freddy has very good programming skills and deals mainly with IDL among other programming languages. He has developed several key programs for research and quality control purposes. Freddy has been with us since April 2002 and started his studies in August 2002.

Raquel Orozco
B.Sc. in Meteorology and Graduate Research Assistant
Raquel was born in Lima, Peru. She has a degree in Meteorology and she's pursuing her Masters in Geography at OU. She participates in all the projects as well. She has worked a lot with the SALLJEX and the NAME projects both in the observational and post-processing campaigns. Raquel has very good organizational and artistic skills. She has worked on and off with us since 2002 and started her studies in August 2004.

José Gálvez
M.Sc. in Meteorology and Researcher Assistant
Jose's from Lima, Peru. He's working on his PhD in Meteorology at the University of Oklahoma. Works mainly with observations and analyses from South America and also with the WRF Model. His Master's thesis research topic was the "Modulation of rainfall by the South American Altiplano lakes". Jose has participated in all of the group's projects (NAMMA, PACS-SONET, NAME and SALLJEX) on data processing, webpage design, observer training and field work. He takes care of the website together with Javier, Raquel and Freddy.
