Intensive cyclones of the Northwest Pacific / Kotovich N.G., Vasilevskaya L.N., Fil A.S., Krokhin V.V. // Hydrometeorological Research and Forecasting, 2020, no. 1 (375), pp. 48-64.

The intense cyclones of the Northwest Pacific originating in the subtropical (subtropical ones) and mid-latitude (southeastern Eurasia and the seas adjacent to it) zones in the winter of 1996-2018 are studied. The main signs for the identification of such cyclones are the explosive nature of their development and the presence of a warm core in the lower or upper troposphere. The assessment of the thermal and vertical structure of the vortices is carried out by the method of R. Hart. A classification of the intensive winter cyclones of the Northwest Pacific has been developed, which is based on the areas of their generation and on the thermal state in the process of development. It is shown that the Hart method allows determining the presence and evolution of the warm core based on the modern numerical models, in particular, the HWRF model.
