The multiscale tropical deep convective variability over the Pacific Ocean is examined with the 4-month highresolution deep convection index ( ) derived from satellite imagery. With a systemic view, the complex ITBB phenomenon is described with succinct parameters known as generalized dimensions associated with the correlation structures embedded in the observed time series, with higher-order d...

The intraseasonal fluctuations of Indian summer monsoon rainfall (ISMR) are mainly controlled by northward propagating oscillation (MISO) and eastward Madden Julian (MJO). In the current study, we examine relationship between (active break spells) ISMR with phase propagation amplitude MISO MJO. We notice that active spells generally occur during phases 2–5 (MJO 3–6), 6–8 1). association active/...

today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...

[1] We investigate the modulation of aerosols by the Madden-Julian Oscillation (MJO) using multiple, global satellite aerosol products: aerosol index (AI) from the Total Ozone Mapping Spectrometer (TOMS) on Nimbus-7, and aerosol optical thickness (AOT) from the Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra and Aqua and the Advanced Very High Resolution Radiometer (AVHRR) on NOA...

The observed convective adjustment time (CAT) associated with Madden–Julian Oscillation (MJO) precipitation is found to vary significantly in space. Here, we investigate the effect of different spatial distributions of CAT on MJO precipitation based on the frictional coupled dynamics moisture (FCDM) model. The results show that a large value of CAT tends to decrease the frequency and growth rat...

The Madden-Julian oscillation (MJO) is the dominant mode of variability in the tropical atmosphere on intraseasonal timescales and planetary spatial scales. Despite the primary importance of the MJO and the decades of research progress since its original discovery, a generally accepted theory for its essential mechanisms has remained elusive. Here, we present a minimal dynamical model for the M...

In Part I of this study it was shown that moving from a moisture-convergentto a relative-humidity-dependent organized entrainment rate in the formulation for deep convection was responsible for significant advances in the simulation of the Madden–Julian Oscillation (MJO) in the ECMWF model. However, the application of traditional MJO diagnostics were not adequate to understand why changing the ...

Negative Polarity Items (NPIs) are known to be licensed in wh-questions. But not all wh-questions behave alike with respect to NPI licensing. As pointed out in Han and Siegel (1996), while all argument wh-questions with NPIs can have a RHETORICAL QUESTION reading, only a subset of them can have a true wh-question reading. In this paper, we point out that adjunct wh-questions with NPIs cannot ha...
