Does the leap in June this year have an impact on the climate this year?

It doesn't matter much. It is hot in some places this year because the subtropical high is too strong, and the El Ni? o phenomenon has appeared.

Leap month is a way to set a leap month in a calendar. In Asia (especially in China), leap month refers to one month added every leap year in the Chinese calendar (also known as the lunar calendar) (in order to coordinate the contradiction between the tropic year and the Chinese calendar and prevent the tropic year from being out of touch with the four seasons, 1 leap is set every two to three years. In ancient times, 19 leap week was used, and Linde calendar was abolished in Tang Dynasty. Sometimes leap month also refers to the month that includes leap day in leap year of Gregorian calendar (especially in February of leap year of Gregorian calendar).

Subtropical high, a meteorological term, also known as subtropical high, subtropical high and subtropical high ridge, refers to a warm and high pressure system located in subtropical areas. In the subtropical region of the northern and southern hemispheres, due to the influence of land and ocean, the high pressure area is often divided into several high pressure units, forming a discontinuous high pressure area distributed along the latitude circle, which is collectively called subtropical high. Subtropical high pressure plays an important role in the transport and balance of water vapor, heat and energy between middle and high latitudes.

Subtropical high plays an important role in the transport and balance of water vapor, heat and energy between middle and high latitudes, and is an important system of atmospheric circulation.

As far as the subtropical high is concerned, the vertical motion of the atmosphere between the east and the west is quite different: in the east of the high, the sinking motion is particularly strong, and the descending airflow is heated by adiabatic compression, resulting in a strong subsidence inversion, which is called trade wind inversion. This strong inversion stratification is very stable, which inhibits the development of vertical convection, makes the weather continue to be fine, and forms a dry climate zone on the west coast of subtropical continent.

The western part of subtropical high is the convergence and rising area of low-level warm and humid air, which is prone to thunderstorm weather.

With the change of seasons, the intensity and location of subtropical high will also change obviously between seasons. From June to July, 65438, the main body of subtropical high in the northern hemisphere moved northward and westward, and its intensity increased. In July-65438+10, the main body of the subtropical high moved from south to east, and its intensity weakened. This seasonal change also has obvious stages of slow change and sudden change.

El Nino? O phenomenon), also known as El Nino flow, is a climatic phenomenon caused by the eastward shift of Walker circulation circle, which leads to the imbalance between the ocean and the atmosphere in the equatorial belt of the Pacific Ocean. Under normal circumstances, the monsoon air flow in the tropical Pacific moves from America to Asia, keeping the surface of the Pacific Ocean warm and bringing tropical rainfall around Indonesia. However, this pattern is disturbed every 2-7 years, and the wind direction and ocean current are reversed. The heat flow in the surface of the Pacific Ocean turns eastward to America, and then takes away tropical rainfall, resulting in the so-called "El Ni? o phenomenon". Because this phenomenon often happens around Christmas at the end of the year, the locals call it "El Nino". When El Nino occurs, because the water temperature is high, plankton is reduced, and fish can't get food and die in large numbers, so seabirds who feed on fish will also die or migrate.

Under normal circumstances, the monsoon air flow in the tropical Pacific moves from America to Asia, keeping the surface of the Pacific Ocean warm and bringing tropical rainfall around Indonesia. However, this pattern is disturbed every 2-7 years, and the wind direction and ocean current are reversed. The heat flow in the surface of the Pacific Ocean turns eastward to America, and then takes away tropical rainfall, resulting in the so-called "El Ni? o phenomenon".

This phenomenon is essentially driven by ocean dynamics, and the corresponding atmospheric change is determined by sea surface temperature (in turn, atmospheric change will strengthen the distribution pattern of ocean temperature), and the distribution of sea surface temperature is determined by ocean dynamics, so the El Ni? o phenomenon represented by the above simplified model is predictable in nature.
