The first thing we have to underline is the etymological origin of the term trough that now occupies us in order to be able to arrive earlier at the discovery of its meaning. In this case, it must be emphasized that it derives from Latin, from “vacuus” which can be translated as “empty” and that it comes, in turn, from the verb “vacare”, which is synonymous with “being empty”.
It is known as vaguada to the line that marks the industry's deep in the valleys or the channel of the river. It is the line that connects the points that are at a lower height: the natural water currents flow through there.
Also known as a talweg from a German term, the trough exhibits a shift to the right in the southern hemisphere and to the left in the northern hemisphere. This is due to the so-called Coriolis effect, which is a consequence of the movement that planet Earth makes when rotating.
In the field of meteorology, it is called a low trough of atmospheric pressure that is registered between two sectors that have high pressure. This barometric depression therefore resembles a valley. A trough occurs when a warm, humid air mass rises through a low-pressure sector, located between two higher-pressure sectors with colder air masses. This phenomenon causes clouds that develop vertically and precipitation.
It is important to know that, within the meteorological field, it is determined that, based on the origin of the atmospheric trough and its characteristics, it can be very similar to what is known as a hurricane, saving distances of course.
The coastal trough develops in South America. The phenomenon is generated in front of a coastal area, where a low pressure sector develops. When it moves eastward, it causes other air masses to descend from the slopes of the Andes Mountains.
Finally, La Vaguada is the name of a neighborhood in the Spanish city of Malaga.
Not forgetting that, in addition, La Vaguada is the name of one of the most important shopping centers in Madrid. It is located in the Pilar neighborhood and is considered to be the first of its kind to be opened in the Spanish capital.
César Manrique was the one who proceeded to design this shopping center, which initially counted on the opposition of the neighbors because they believed that it would end small businesses. However, later they decided to support its construction in view of the job offers that it was going to put up as well as the public and cultural spaces that it was going to house in its facilities.
It was inaugurated in 1983, has a total of five floors, was remodeled in 2008 and offers a wide variety of establishments, both hypermarkets and small shops, traditional markets, cinemas and high-value services such as the Post Office or pharmacies.
