This study aims to analyze the vertical structure of the terms of the ECT balance equation for the occurrence of intermittent events generated in surface and propagate upward. In order to verify that the dominant terms and the role of each term during such events. It was used FLOSSII experimental data collected in seven vertical levels (1 m, 2 m, 5 m, 10 m, 15 m, 20 m and 30 m) and have a sampling frequency of 60 Hz. The study period comprises between 20 November 2002 to 02 April 2003 and of that total, this study, we analyzed 108 nights. The majority of events generated surface (EB) are very weak compared to the events generated at the top of the tower layer and propagate down. The analyzes made by vertical turbulence structure and ECT balance for the EB’s showed that the dominant term near surface is the mechanical production. Thus, with increasing shear surface, producing turbulence and consequently, the transport of works term “loading” turbulence to higher levels of the atmosphere.

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.
In particular,
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 An Editor must not use unpublished information in the editor's own research without the express written consent of the Author.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.
