abstract = "Gravity waves observed in the troposphere play an important role
in the transport of energy and momentum between lower and middle
atmosphere, changing the thermal structure and general circulation
in these regions. However, gravity waves generated by tropical
convection are generally not well simulated in global circulation
models, remaining as an area of science that deserves research and
investment. The use of models capable of explicitly solving
moisture transport and heating associated with convective clouds
is relatively recent, as well as applications of data assimilation
on this scale. On the other hand, only a few observation systems
have a high vertical resolution and sample the upper troposphere
and lower stratosphere, making difficult to obtain a detailed
description of the spectrum of gravity waves generated by deep
convection. Observations derived from the radio occultation (RO)
of the Global positioning system (GPS) signals are able to assist
in this task and have been explored to study atmospheric waves and
coupling processes, especially in regions where ground-based
temperature profiles are not provided. The high vertical
resolution of temperature profiles derived from GPS RO technique
and its global coverage, allowed to study the mesoscale
temperature fluctuations caused by atmospheric waves in the
stratosphere as well as analyze internal parameters of gravity
waves. The present study aims to review previus works on the use
of GPS RO profiles to explore gravity waves characteristics. Some
results of the gravity waves activity in South America will be
presented.",
