Global and Regional Characteristics of Radially Outward Propagating Tropical Cyclone Diurnal Pulses

Abstract

Tropical cyclones (TCs) are one of the most catastrophic natural hazards, causing thousands of deaths and billions of dollars in economic losses every year (

Diurnal Variations on the Initiation Time and Intensification Rate of Rapidly Intensifying Tropical Cyclones

“…Previous studies found that the initiation of the diurnal pulse is closely linked to a strong IR BT cooling signal within the inner core, which may imply the fast developing of the inner-core deep convection and the RI of TCs (X. Zhang et al, 2023;X. Zhang & Xu, 2021b).…”

“…The inner‐core IR BT cooling rate represents how fast the convection is developing (Dunion et al., 2014; X. Zhang & Xu, 2021b). Previous studies found that the initiation of the diurnal pulse is closely linked to a strong IR BT cooling signal within the inner core, which may imply the fast developing of the inner‐core deep convection and the RI of TCs (X. Zhang et al., 2023; X. Zhang & Xu, 2021b). The surface precipitation can be a proxy of the convection through the deep layer of the troposphere (Leppert & Cecil, 2016; X. Zhang & Xu, 2022).…”
