Abstract

In this investigation is carried out a study on the processes mesoescalares of the territory Sancti Spíritus,
Ciego de Ávila and Camagüey in the rainy period of the year, understood in the decade between 1984 and 1993. It defines the concept of Environment of
the Gradient of Pressure in Surface, (EGPS), and the groups that conform it for each bimestre, starting from which the particularities are studied from the
field of wind to mesoescala in the schedule of the 18 UTC and the distribution from the field of probabilities of superior precipitations over 0.1 mm, for each
one of the bimestres of the period, conformed by: May-June, july-August and September-October. It is also defined for each one of the EGPS, the concept of
Associated Circulation Patterns, (ACP), starting from which is possible to establish the nexus between the conditions mesoescalares of the field of wind and the
precipitations. In the investigation the concept of the Line of Fork is perfected from the Flow to Mesoescala (LCFM) when carrying out a wider analysis when
integrating other aspects to the treaty as LCFM (concept starting from alone the address of the wind), such as the force of the wind to consider the convergence
of the wind (that which seen in its interaction; address and Speed of the wind, allow to speak of convection) and the precipitations; considering the
above-mentioned establishes a new concept when denominating to this typical process of the summer or rainy period in Cuba like Area of Maximum Convection
in the Flow to Mesoescala (ZMCFM), which adopts specific configurations in dependence of each EGPS, with the consequent behavior of the time to
mesoescala. It is approached in detail the characteristics as for the location and structure from the field of wind to mesoescala, with relationship to the
address of the synoptic flow of the groups of EGPS for each bimestre. The particularities are discussed from the PCAs to the EGPS in general. Chart, figures
and graphics are included in form of mosaic that you/ they illustrate the content of the investigation.
