Horizontal winds in the mesosphere have been measured over Ascension Island (8° S, 14°
W) in the tropical mid-Atlantic region throughout the years 2002–2011. The observations …

In the present work, we analyze the competition between tidal winds and electric fields in the
formation of blanketing sporadic E layers (Es b) over São Luís, Brazil (2° 31′ S, 44° 16 …

Mesospheric winds have been measured by meteor radar at Cachoeira Paulista (22.7° S;
45° W) since April 1999. The tidal components were analyzed over about 21 years of …

The advantages of using a composite day analysis for all-sky interferometric meteor radars
when measuring mean winds and tides are widely known. On the other hand, problems …

Sporadic E (E s) layers are patches of high ionization observed at around 100–140 km
height in the E region. Their formation at low latitudes is primarily associated with the diurnal …

The paper presents climatology of the mean winds and diurnal and semidiurnal tides
observed by meteor radars at high latitudinal stations Svalbard (78° N, 16° E) and Tromsø …

Seasonal variations of different tides in the mesosphere and lower thermosphere are
investigated from wind observations of a meteor radar chain on the basis of Hough mode …

In this work, we have performed a study for the first time on the climatology of the
intermediate descending layers (ILs) over Brazilian equatorial and low-latitude regions …

A mesospheric front was observed with an all-sky airglow imager on the night of 9–10 July
2007 at Ferraz Station (62° S, 58° W), located on King George island on the Antarctic …

Zonal winds in the stratosphere and mesosphere play important roles in atmospheric
dynamics and aeronomy. However, the direct measurement of winds in this height range is …
