SOUZA, Enio P.; LEITAO, Mário M. V. B. R.  y  BARBOSA, Tatiane F.. Characteristics of upper atmosphere from high-resolution surface data. Rev. bras. eng. agríc. ambient. [online]. 2001, vol.5, n.3, pp. 463-468. ISSN 1807-1929.

Some parameters of the upper atmosphere are calculated from high-resolution surface data collected in the city of Campina Grande, PB. By verifying ten-minute mean values of temperature, moisture and radiation budget, it is possible to have an idea, in this time resolution, of parameters like: cloud cover effects, cloud base height, convective available potential energy and convection inhibition energy. It is shown how the evolution of these parameters can be used as a meteorological analysis tool. The presence of clouds changes the values of the parameters that can be estimated from surface data.

Palabras clave : surface data; CAPE; weather.
