A statistical model (relationship) between a new circulation instability index and the registered temperature anomalies in two regions of Europe has been proposed tested. The average values this index, calculated at levels 850 hPa 500 hPa, were used as predictors modelling by months for period 2011–2020. monthly geopotential during utilized to calculate these regions. For each them, following c...

Abstract The predictability limit of the Madden‐Julian Oscillation (MJO) in El Niño and La Niña boreal winters (November‐February) is investigated using observational data historical run outputs CMIP models. MJO computed by nonlinear local Lyapunov exponents approach for various indices obtained from bandpass‐filtered (30–80 days) outgoing longwave radiation, 850‐hPa zonal wind, 200‐hPa wind da...

In order to better understand the formation mechanism of rainstorm in China and promote disaster prevention reduction, based on meteorological data National Meteorological Information Center Japan Agency, this paper draws isobaric surface map 850 hPa 500 hPa, relative humidity precipitation distribution map. study, synoptic methods were used analyze heavy process North from August 23th 24th, 20...

Monsoon onset over the Kerala (MOK) coast has been studied using the recently released high resolution Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite data (HOAPS 3). Columnar water vapour content, sea surface temperature and evaporation have been utilised to examine the conditions leading to MOK from 7 pentads. The role of monsoon hadley cell (MHC) has also been assessed using th...

A physics-based statistical stochastic system is developed for estimating the long-term hazard of rare, high impact landfall events globally from ensembles of synthetic tropical cyclones. There are three components representing the complete storm lifetime: an index-based genesis model, a beta-advection track model and an autoregressive intensity model. All three components depend upon the local...

We present analyses of a lacustrine sediment core (DY6) on Dongdao Island, which provides high-resolution paleoclimate records for the South China Sea (SCS). Results of element analyses indicate that the concentrations of Ti and Al in DY6 are much higher than the background on the island. Morphological characteristics of acidic insoluble particles are similar to aeolian in East China. Sr and Nd...

[1] This study estimates the amplitude and phase of the climatological diurnal cycle of temperature, from the surface to 10 hPa. The analysis is based on four-times-daily radiosonde data from 53 stations in four regions in the Northern Hemisphere, equatorial soundings from the Tropical Ocean Global Atmosphere/Coupled Ocean Atmosphere Response Experiment, and more recent eight-times-daily radios...
