Observation of TGFs at Mid Latitude
2021<p>We present a sample of Terrestrial Gamma-ray Flashes (TGFs) observed at mid latitudes by the Atmosphere Space Interaction Monitor (ASIM). The events were detected over the period June 2018 - August 2020 in the latitude bands between 35&#176; and 51&#176; and between -35&#176; and -51&#176;; the sample ...

Mid-latitude glaciation on Mars
Progress in Physical Geography: Earth and Environment, 2012Near-surface water ice, either pure or mixed with regolith, forms a widespread suite of distinctive landforms in Mars’ mid-latitudes. These landforms are in many cases sufficiently similar to cryospheric features on Earth to allow analogue-based comparisons to be made.

Mid‐latitude mesoscale variability
Reviews of Geophysics, 1983Neither homogeneous quasi‐geostrophic turbulence nor the effect of eddies on the interior ocean circulation remains the major focus of mesoscale research as was the case for much of the preceding 20 years following identification of the phenomena. Concentration on basin‐wide geographical exploration of eddy properties was rather well established by ...

The Mid-Latitude Trough-Revisited
2013The mid-latitude trough is a major feature of the F-region ionosphere that forms at the boundary between the mid-latitude and auroral ionospheres. The trough region has a major influence on the propagation of radio waves because of the large gradients in electron concentration, and the irregularities often embedded in the equatorward and poleward walls

Habitable periglacial landscapes in martian mid-latitudes
Icarus, 2012Subsurface permafrost environments on Mars are considered to be zones where extant life could have survived. For the identification of possible habitats it is important to understand periglacial landscape evolution and related subsurface and environmental conditions.

The observed ozone trend in percentage change per decade as a function of latitude and season from 1978 to 1991 is shown in Figure 1. In addition to polar ozone depletion, the unshaded areas in Figure 1 show that ozone depletion of 5% to 8% per decade has occurred at mid-latitudes in both hemispheres. The observed vertical profile (Fig.

Mid-latitude pulsating auroras
Planetary and Space Science, 1974Pulsating auroras were recorded at Bedford, Massachusetts, cgm lat. 55.4°, 24 March 1969 during a worldwide magnetic storm, the only known published observations of pulsating auroras at such low magnetic latitudes. Spectral density analysis of several minutes of 5577A pulsations indicated a dominant period of 7.2 sec at 0300 EST.

Large dune fields, or sand seas, are landscapes often thought to be found only in deserts beneath the great, subtropical high-pressure zones, where subsiding air suppresses rainfall. Dune fields are also quite common in mid-latitude regions, to the north and south of subtropical deserts (Fig. 1).

The structure of rainbands within a mid-latitude depression
Quarterly Journal of the Royal Meteorological Society, 1973AbstractA case study is presented of a winter depression over the British Isles in which extensive banded structure was observed within precipitation ahead of the surface warm front. Measurements of the mesoscale airflow and precipitation structure of the rainbands were made using a variety of radar techniques together with multiple radiosonde and ...

The Mid-Latitude Trough. A Review
1992Abstract : The mid-latitude trough is a depletion of F-region electron densities at sub-auroral latitudes which are mostly seen as a nocturnal feature usually located between invariant latitudes 55 and 75 degrees. In this report, a review of past literature outlining the characteristics of the mid-latitude trough is presented.
