Recent decrease in inner‐core rain rate of tropical cyclones over the western North Pacific

Atmospheric Science Letters, 2022
The tendency in tropical cyclone (TC) rainfall is of great concern due to its remarkable contribution to global precipitation and extreme rainfall events. This study finds a decreasing trend in TC inner‐core rain rate over the western North Pacific (WNP)

Fe alloy slurry and a compacting cumulate pile across Earth's inner-core boundary

, 2019
Seismic observations show a reduced compressional-wave gradient at the base of the outer core relative to the preliminary reference Earth model and seismic wave asymmetry between the east-west hemispheres at the top of the inner core.

Inverse problem for the Earth's core evolution model

Russian Journal of Earth Sciences, 2020
The size and the age of the inner core impose constraints in modeling of the Earth's core evolution. The origin of the solid core corresponds to the change in convection regime in the core and, correspondingly, to the change in the magnetic field ...

Fe-C and Fe-H systems at pressures of the Earth's inner core

, 2012
The solid inner core of the Earth is predominantly composed of iron alloyed with several percent Ni and some lighter elements, Si, S, O, H, and C being the prime candidates.

Fe Melting Transition: Electrical Resistivity, Thermal Conductivity, and Heat Flow at the Inner Core Boundaries of Mercury and Ganymede

Crystals, 2019
The electrical resistivity and thermal conductivity behavior of Fe at core conditions are important for understanding planetary interior thermal evolution as well as characterizing the generation and sustainability of planetary dynamos.

The axial ratio of hcp iron at the conditions of the Earth's inner core

, 2004
We present ab initio calculations of the high-temperature axial c/a ratio of hexagonal-close-packed (hcp) iron at Earth's core pressures, in order to help interpret the observed seismic anisotropy of the inner core.

Compaction‐Driven Convection in the Growing Inner Core

Geophysical Research Letters
The Earth's inner core (IC) is known to exhibit heterogeneous structures with their origins still unknown. From the onset of nucleation, the IC can grow via sedimentation and compaction of iron crystals freezing out from the fluid outer core.

A Review of Typhoon Inner Core Characteristics and Their Relationship with Intensity Changes

Atmosphere
The inner core of a typhoon plays a crucial role in storm intensification and is especially critical for rapid increases in storm intensity. Most of the energy exchange occurs in the inner core, including the eyewall. Moist air rising from the warm ocean

A Numerical Study on Turbulent Couette Flow and Heat Transfer in Concentric Annuli by Means of Reynolds Stress Turbulence Model

International Journal of Rotating Machinery, 1995
A numerical study is performed to investigate fluid flow and heat transfer characteristics in a concentric annulus with a slightly heated inner core moving in the flow direction and a stationary, insulated outer cylinder. Emphasis is placed on the effect
