Shock Wind Loads on Tall Buildings and Quantum Laws of the Wind Formation

According to the latest report of the UN intergovernmental panel on climate change (IPCC) almost all Nations of the world are not ready for precautionary measures on vitally important sectors of economy and population adaptation to global warming.

On the other hand, for example, Mottaki Nakamura of Japan’s national Agency for marine research and a number of Russian and European scientists said that mankind should not prepare to global warming and global cooling.

The lack of progress and a common position for the world’s leading scientific schools on the global climate change issue poses a particularly difficult situation of the construction industry practical of all States, including countries with highly developed economies.

The relationship of this problem with the construction activity and its acuteness follows from direct dependence of design decisions from the global climate change risks assessment on the urban planning depth. For example, on the life of construction objects, which, as a rule, reach 100 and more years. That is for the period until 2114 year and next. Especially important to take into account extreme climatic processes, including wind, for building construction. Thus, this problem acuteness for the construction industry not only theoretical problems of scientific discussions, and has the most direct practical meaning.

Construction activity in the world, connected with many trillions of dollars of long-term investments cannot stop because of differences in meteorological science schools. This is due to the daily necessity of such design solutions selection that will provide the necessary security and stability of building structures to all forms of climatic and meteorological loads and impacts for a long period in the life cycle of industrial and civil construction objects.

Among such loads special place wind load, which is characterized as average daily wind speed and the maximum speed of the shock wind effects on building structures. Theoretical meteorology over the last hundred years was focused mainly on statistical studies of the wind processes structure. Labour-intensive statistical methods of research historically have an important place in almost all physics branches. But we must bear in mind that its application, as a rule, is connected not so much with his uniqueness, as with the mathematical physics analytical methods difficulties.

It is also associated with the presence of the studied processes are poorly understood or previously unknown phenomena, effects and patterns. In our opinion, the period of mainly statistical modeling in theoretical meteorology was delayed. In the last decade the classical laws of aerodynamics, thermodynamics and heat mass transfer, with not very significant additions and a practically unchanged from the theoretical basis of modern software systems modeling and meteorological processes forecasting.
