Megaphone: Latency-conscious state migration for distributed streaming dataflows

open access: yes, 2019
We design and implement Megaphone, a data migration mechanism for stateful distributed dataflow engines with latency objectives. When compared to existing migration mechanisms, Megaphone has the following differentiating characteristics: (i) migrations ...

Effects of diabatic heating on the ageostrophic circulation of an upper tropospheric jet streak [PDF]

open access: yes
Interaction between the mass circulation within a mesoscale convective complex (MCC) and a direct mass circulation in the entrance region of an upper tropospheric polar jet streak was examined within the isentropic structure to investigate mechanisms ...

Model simulations of complex dust emissions over the Sahara during the West African monsoon onset [PDF]

open access: yes, 2012
The existing limitations in ground-based observations in remote areas in West Africa determine the dependence on numerical models to represent the atmospheric mechanisms that contribute to dust outbreaks at different space-time scales.

Urban Impacts on Convective Squall Lines over Chicago in the Warm Season—Part II: A Numerical Study of Urban Infrastructure Effects on the Evolution of City-Scale Convection

open access: yesAtmosphere
Numerical models were employed to simulate the effects of urban infrastructure on the city-scale precipitation distribution during multiple closely occurring convective squall line events over Chicago. Two high-resolution simulations were inter-compared,

Preliminary Study on the Feasibility of Performing Quantitative Precipitation Estimation Using X-band Radar [PDF]

open access: yes
IRCTR has built an experimental X-band Doppler po-larimetric weather radar system aimed at obtaining high temporal and spatial resolution measurements of precipitation, with particular interest in light rain and drizzle. In this paper a first analysis of

Causality analysis of a disaster-causing squall line event on 24 September in southeastern Inner Mongolia

open access: yes暴雨灾害, 2019
Based on the conventional observation data, automatic weather station data, Doppler radar data and NCEP(0.25°×0.25°) reanalysis data, a strong convective weather event occurred in the southeastern Inner Mongolia on 24 September 2016 caused by the ...
