Characterization of water availability in a hydrographic basin REA
Arai,Fabiane K.; Pereira,Silvio B.; Gonçalves,Geula G. G..
The quantitative knowledge of hydrological parameters (rainfall and flow) and their spatial and temporal variability on the regions or basins should be understood as essential to the efficient planning and management of water resources. Because the Ivinhema Basin, located in the state of Mato Grosso do Sul, Brazil, represents an important inductor on the region agricultural development, characterized as a major producer of grains and meat, it was used to characterize the hydrological study. Knowing the rainfall, flow and drainage area of each of the studied affluent, it was calculated the proportion of contribution of the affluent. To that end, it was proposed the concepts of potential and real contributions, aiming to identify the proportion of...

Apport des donnees TRMM 3B42 a l´etude des precipitations au Mato Grosso. Repositório Alice
ARVOR, D.; DUBREUIL, V.; RONCHAIL, J.; MEIRELLES, M. S. P..
In tropical regions where convective rainfall is predominant while raingauge networks are deficient, satellite estimates as proposed by the Tropical Rainfall Measuring Mission (TRMM) can represent an efficient alternative way of studying rainfall spatiotemporal variability. A Principal Component Analysis based on monthly data allows mapping the various rainy regimes encountered in the south Amazonian state of Mato Grosso (Brazil). The TRMM 3B42 products are then validated based on statistical indexes. It permits determining an optimal 5-days temporal scale, which is then used to calculate rainy season parameters such as date of onset and end and duration. Those parameters are established based on the ?Anomalous Accumulation? method proposed by Liebmann...

Time distribution of heavy rainfall events in Urussanga, Santa Catarina State, Brazil - doi: 10.4025/actasciagron.v33i4.6664 Agronomy
Back, Álvaro José; Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina.
A knowledge of rainfall time distribution is important for several types of hydrological studies related to surface runoff. This study aims to determine the time distribution pattern of heavy rain events in Urussanga, Santa Catarina State, Brazil. It employed recording rainfall charts from the meteorological station of Urussanga (latitude: 28.31° S, longitude: 49.19° W, altitude: 49 m) from 1980 to 2007. Rain events were classified into four types according to the duration quartile in which the greatest amount of precipitation occurred. It is found that type I rain events are more frequent, followed by type II, and these occur predominantly during the summer, while type III and IV rain events are distributed throughout the year. In the summer, rain events...

Using Sea Surface Temperatures to Predict Seasonal Rainfall over East OceanDocs
Bazira, E..
In East Africa (Uganda, Kenya and Tanzania) agriculture sector employs over 80% of the work force and export earnings from the sector constitute a major part of the national budgets. Subsistence farming is the major source of food. However food shortages as well as negative impacts on several sectors of the economies have been attributed to the seasonal weather variations among other factors. Therefore, the objective of this study was to determine the Long-Range prediction potential of seasonal rainfall as derived from SST modes of the neighboring oceans.

Maize yield and rainfall on different spatial and temporal scales in Southern Brazil Repositório Alice
BERGAMASCHI, H.; WHEELER, T.R.; CHALLINOR, A.J.; COMIRAN, F.; HECKLER, B.M.M..
This study aimed to establish relationships between maize yield and rainfall on different temporal and spatial scales, in order to provide a basis for crop monitoring and modelling. A 16-year series of maize yield and daily rainfall from 11 municipalities and micro-regions of Rio Grande do Sul State was used. Correlation and regression analyses were used to determine associations between crop yield and rainfall for the entire crop cycle, from tasseling to 30 days after, and from 5 days before tasseling to 40 days after. Close relationships between maize yield and rainfall were found, particularly during the reproductive period (45-day period comprising the flowering and grain filling). Relationships were closer on a regional scale than at smaller scales....

Are Brazil nut populations threatened by fruit harvest? Repositório Alice
BERTWELL, T. D.; KAINER, K. A.; CROPPER JUNIOR, W. P.; STAUDHAMMER, C. L.; WADT, L. H. de O..
Harvest of Brazil nuts from the large, iconic tree Bertholletia excelsa generates substantial income for smallholders, providing a strong incentive to conserve the mature forests where it grows. Although much previous work has focused on the impact of nut harvest on new seedling recruits into B. excelsa populations, the connection between harvest rates and long-term population stability is still unclear. Moreover, there is additional uncertainty for Brazil nut management in terms of population response to climate change and other anthropogenic influences. We drew on 14 years of research in two sites in Acre, Brazil with different B. excelsa nut harvest intensities (39% and 81%), to produce stochastic and deterministic matrix population models which...

The succession dynamics of a macroalgal community after a flood disturbance in a tropical stream from São Paulo State, southeastern Brazil Rev. Bras. Bot.
Branco,Ciro Cesar Z.; Branco,Luis Henrique Z.; Moura,Maurício Osvaldo; Bertusso,Fernando Rodrigo.
The succession dynamics of a macroalgal community in a tropical stream (20º58' S and 49º25' W) was investigated after disturbance by a sequence of intensive rains. High precipitation levels caused almost complete loss of the macroalgal community attached to the substratum and provided a strong pressure against its immediate re-establishment. After this disturbance, a weekly sampling program from May 1999 to January 2000 was established to investigate macroalgal recolonization. The community changed greatly throughout the succession process. The number of species varied from one to seven per sampling. Global abundance of macroalgal community did not reveal a consistent temporal pattern of variation. In early succession stages, the morphological form of...

Weed emergence in autumn under temperate conditions Planta Daninha
Calado,J.M.G.; Basch,G.; Carvalho,M..
The emergence of weed plants depends on environmental conditions, especially temperature and soil moisture. The latter is extremely important in Mediterranean environments which are characterized by irregular amount and distribution of rain throughout the year, which influences the beginning of the growth cycle of the annual species (seed germination). This paper studies the influence of rainfall, in particular accumulated rainfall in autumn, on the emergence of weed plants. The experiment was carried out on Luvisols, and the appearance of flora under field conditions was observed. Through analysis of the results, it can be concluded that a high percentage of weed plants (> 85% related to the highest registered value) was obtained with more than 90 mm...

Precipitação no quadrimestre chuvoso na região do bioma Caatinga e a relação com a temperatura da superfície do mar. Repositório Alice
CUADRA, S. V.; VICTORIA, D. de C.; OLIVEIRA, A. F. de; REBOITA, M. S.; MONTEIRO, J. E. B. de A..
RESUMO. Foram objetivos desse estudo analisar o total precipitado no quadrimestre chuvoso e definir, com a técnica de regressão linear, equações preditivas para a precipitação no Bioma Caatinga. Para tanto, as variáveis independentes utilizadas foram a temperatura da superfície do mar (TSM) na região de Niño 3.4 no oceano Pacífico Tropical e na região do dipolo de TSM do Atlântico Tropical. Os resultados mostraram que a precipitação na maior parte da Caatinga é melhor prevista com base na TSM do Atlântico, enquanto que o setor norte do nordeste do Brasil é afetado também pela TSM do Pacífico. Em diversas regiões os volumes precipitados ao longo do quadrimestre chuvoso são inferiores a 400 mm, o que resultaria em perdas para diversas culturas anuais, como o...
