CLIMATOLOGY OF MESOSCALE CONVECTIVE SYSTEMS OCCURRING OVER SOUTH AMERICA IN THE PERIOD 2005 – 2006
Keywords:Mesoscale convective systems. Complex convective systems
In order to document the frequency and morfological features of Mesoscale Convective Systems (MCSs) over Southern South América between 2005-2006, a short climatology is presented. Using GOES-13 Satellite data and and automatic strom track classification procedure, 33 MCSs events were identified and cataloged following its excentricity. 60% of cases were classified as MCSs enlongated and 40% as MCSs circular/ or Mesoscale Convective Complexes (MCCs). The data analysis shows the MCSs higher frequency relatively to MCCs, cover larger areas, and also longest life time. In average time life of 44h for SCMs, and 26h for CCMs. Therefore, SCMs enlongated create a higher socio-economical impacts than MCCs, being more significant for Souther South America hidrological cycle.

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
