A espacialização dos sistemas atmosféricos e a análise rítmica para o centro-sul do Brasil

Abstract

O objetivo do estudo foi quantificar e qualificar a espacialização temporal e a evolução dos sistemas atmosféricos para o Centro Sul do Brasil, por meio da Análise Rítmica, a partir de quatro localidades: Campo Mourão PR, Cáceres MT, Brasília DF e Caparaó MG. Escolheu-se o mês de julho de 2005. Julho é um mês característico da estação do inverno, e 2005, ano neutro, considerando o El Niño e a La Niña. A dinâmica atmosférica para essa região, na estação do inverno, é comandada pelas massas de ar Polar atlântica, Tropical atlântica, Tropical continental e sistema frontal, basicamente. A massa Tropical continental atua limitadamente a partir do oeste da região. Os principais episódios de chuva foram frontais, e a altura decresce do sul para o norte. Como essa região não é centro de origem de qualquer sistema atmosférico, ela se caracteriza como uma região terminal ou dissipatória, ou seja, onde as massas de ar se modificam. Por essa razão, todos os sistemas que atuam, modificam-se à medida que avançam, assim como diminui a participação cronológica no estado do tempo

Atmospheric Patterns in Porto Velho, Rondônia, Southwestern Amazon, in a Rhythmic Context between 2017 and 2018

“…In the transition season from the rainy to the dry season, the weather conditions are influenced by the mEc type air mass and with some episodes of the entrance of the third branch of the air mass mPa, known regionally as coldness ("friagem"). Borsato and Mendonça [19] reinforce that mPa can advance to the Equator, causing this phenomenon in the Amazon, and the participation of mPa decreases towards the north in time of action and intensity. According to the statistics presented in the climate rhythm graph, April 2018 resulted in high temperatures, allied to the action of the air mass mTc.…”

“…Air temperatur air humidity, wind speed and direction, atmospheric pressure, and precipitation wer obtained using the INMET automatic weather station (A-925), code WMO 81932, locate on the premises of the Brazilian Agricultural Research Corporation (EMBRAPA) (8°47 63°50 W, 87 m) in Porto Velho. The data were tabulated in MS-Excel ® , version 201 followed by the graphical analysis in the free program RÍTMOANÁLISE [19] The climate database was organized in two stages of the research. Air temperature, air humidity, wind speed and direction, atmospheric pressure, and precipitation were obtained using the INMET automatic weather station (A-925), code WMO 81932, located on the premises of the Brazilian Agricultural Research Corporation (EMBRAPA) (8 • 47 ′ S, 63 • 50 ′ W, 87 m) in Porto Velho.…”

The data were tabulated in MS-Excel ® , version 2013, followed by the graphical analysis in the free program RÍTMOANÁLISE [19] at 12 h UTC (8 h, local time) because the synoptic chart was only available at this time. The climatic data for August showed faults on some days.…”

“…The investigation of the habitual behavior of the air masses and its influence on the climate is the object of the studies whose methodological theoretical basis centers on rhythmic analysis [14][15][16][17]. Rhythm is the essence of Brazilian geographical climatology, which is the interaction between atmospheric circulation and the elements of the climate, analyzed on a daily chronological basis [18,19]. These are investigations established through the climate rhythm proposed by Monteiro [20].…”

Fatal case of spotted fever in a patient from Northeastern Brazil

“…strain Atlantic Rainforest, and mild to moderate disease associated with inoculation swelling and lymphadenopathy 15 , 17 . In contrast, both Sertania municipality and Arcoverde municipality (where the patient resided) lie within the Caatinga biome, in a typical area of the Brazilian semi-arid region 21 . This area lacks any previous known epidemiological context for SF establishment.…”
