What role does the polar jet stream play in the formation of DANA even...

The polar jet stream is a fast-moving wind current that can detach pockets of cold air and allow them to descend over the Mediterranean region. This descent creates a stark temperature contrast with the warm air, causing rapid rises of moist air and leading to the formation of cumulonimbus clouds associated with DANA events. This interaction significantly contributes to the intensity of rainfall experienced during such weather phenomena, demonstrating the complex dynamics of atmospheric elements in weather formation.

Directions: Answer the question based on the following passage.Atmospheric jet streams were discovered towards the end of World War II by U.S. bomber pilots over Japan and by German reconnaissance aircraft over the Mediterranean. The World Meteorological Organisation defines a jet stream as a strong, narrow air current that is concentrated along a nearly horizontal axis in the upper troposphere or stratosphere (10 to 50 km altitud e), characterised by wind motions that produce strong vertical lateral shearing action and featuring one of more velocity maximum. Normally, a jet stream is thousands of kilometers long, hundreds of kilometers wide and several kilometres thick. The vertical wind shear is of the order of 5 to 10 m/sec per kilometre, and the lateral shear is of the order of 5 m/sec per 100 km. An arbitrary lower limit of 30 m/sec is assigned to the speed of the wind along the axis of a jet stream.With abundant radio-sonic data now available over the Northern Hemisphere, it is possible to map the jet streams in the upper troposphere (near 10 to 12 km) in their daily occurrence and variation and to forecast them reasonably well with numerical prediction techniques. Upper-air information from the Southern Hemisphere is still sparse. Constant-level balloons (the so-called GHOST balloons) and satellite information on temperature structure and characteristic cloud formations in the atmosphere are serving to close the data on the global jet stream distribution.The strongest winds known in jet streams have been encountered over Japan, where speeds up to 500 km/hr (close to 300 knots) occur. A persistent band of strong winds occurs during the winter season over this region, flowing from the southwest and leading tropical air northern India into juxtaposition with polar and arctic air from Siberia. A similar region of confluence of air masses with vastly different temperatures exists over the central and eastern United States, leading to a maximum frequency of occurrence of jet streams during winter and spring.The main impact on weather and climate comes from two distinct jet stream system: the polar-Front Jet Stream, which is associated with the air mass contrasts (the fronts) of middle latitudes and which gives rise to the formation of squalls, storms, and cyclones in this latitude belt; and the Subtropical Jet Stream, which lies over the subtropical high-pressure belt, and which is characterized by predominant subsidence motions and, hence, by fair weather. During summer, a belt of strong easterly winds is found over Southeast Asia, India, the Arabian Sea, and tropical Africa, this tropical, easterly jet streams is tied in with the weather disturbances of the Indian and African summer monsoons and their heavy rainfalls.Because of their strong winds, jet streams play an important role in the economy of air traffic. Head winds must be outlasted by extra fuel, which takes up useful cargo space. Clear air turbulence (CAT) is often associated with the strong vertical wind shears found in the jet stream region. It is a hazard to passenger and crew safety, and, because of the increased stresses on the air frame, it decreases the useful life of the aircraft.

The Indian Evidence Act, 1872, provides for situations in which facts otherwise not relevant may become relevant. It is dealt in Section 11 of the Indian Evidence Act, 1872. It reads as, “Facts not otherwise relevant are relevant –– (1) if they are inconsistent with any fact in issue or relevant fact; (2) if by themselves or in connection with other facts they make the existence or non-existence of any fact in issue or relevant fact highly probable or improbable.” If a fact, which is otherwise irrelevant, disproves or tends to prove or disprove a fact in issue or a relevant fact, the irrelevant fact becomes a relevant one. The section is capable of having a wide scope. However, reading the section in an unreasonably broad sense would defeat the purpose of the Evidence Act.Plea of Alibi: There are certain facts which cannot be said to have co-existed with another fact. If one fact is proved to be true for a person, another fact that cannot co-exist with the fact so proved automatically stands disproved. This is the principle behind a concept of alibi according to which if the accused is proved to have been present at a different place at the same time when the offence was committed, it is concluded that the person was not physically present during the commission of the offence. A plea of alibi must be established with absolute certainty. In a case where it was proved that the person was not physically present at the place where the act was alleged to have been committed but was present only a few miles away from such place, the plea of alibi was not allowed. Where the accused claimed that he was present at a different place when the offence was committed but failed to provide proof of the distance between the two places, the plea of alibi was not allowed.The words “highly probable or improbable” used in clause (2) of the section refers to the degree of connection between the fact in issue or relevant fact and a collateral fact. For a fact otherwise not relevant to be relevant under this section, it has to clearly establish the existence or non-existence of a fact in issue or a relevant fact. The degree of probability must be sufficiently high enough and not merely reasonable. In Mahender Singh Dahiya v. State (CBI) case, the husband was accused of killing his wife. The letters written by the wife to the husband were not considered to be relevant under the section since they failed to establish a high degree of probability."Q. In Sarojekumar Chakrabarti v. Emperor, the fact in issue was pertaining to possession of a revolver. An identical revolver was publicly showed by the accused three weeks earlier. Can the fact that an identical revolver was publicly showed by the accused three weeks earlier become relevant though it is nowhere related to the commission of crime by the accused?
