[PDF] Data assimilation of dust aerosol

30.04.2020· A data assimilation system (DAS) was developed for the Chinese Unified Atmospheric Chemistry Environment – Dust (CUACE/Dust) forecast system and applied in the operational forecasts of sand and dust storm (SDS) in spring 2006. The system is based on a three dimensional variational method (3D-Var) and uses extensively the measurements of surface visibility (phenomena) and dust

Earthquake Prediction - an overview |

19.10.1992· Earthquake prediction is a challenging problem requiring a great deal of interdisciplinary research. In principle, there are two major approaches to developing a methodology for earthquake forecasting. The first approach is to search for intricate cause-effect links between earthquakes and the events accompanying them, trying to establish some functional relation among quantitative

Weather forecasting - Wikipedia

History Ancient forecasting. For millennia people have tried to forecast the weather. In 650 BCE, the Babylonians predicted the weather from cloud patterns as well as astrology.In about 350 BCE, Aristotle described weather patterns in Meteorologica. Later, Theophrastus compiled a book on weather forecasting, called the Book of Signs. Chinese weather prediction lore extends at least as far back

New tools for forecasting steam-blast

Until recently, however, monitoring systems have been unable to detect the small-amplitude deformation of deadly eruptions. That challenge has now been met. Tomokazu Kobayashi, Yu Morishita, and Hiroshi Munekane at the Geospatial Information Authority of Japan have detected the telltale crustal deformation in satellite ground deformation data. 1 1.

Inverting the East Asian Dust Emission Fluxes

We present the inversions (back-calculations or optimizations) of dust emissions for a severe winter dust event over East Asia in November 2016. The inversion system based on a fixed-lag ensemble Kalman smoother is newly implemented in the Weather Research and Forecasting model and is coupled with Chemistry (WRF-Chem). The assimilated observations are the hourly aerosol optical depths (AODs

Seasonal Asian Dust Forecasting Using GloSea5

The springtime dust events in Northeast Asia pose many economic, social, and health-related risks. Statistical models in the forecasting of seasonal dust events do not fully account for environmental variations in dust sources due to climate change.

Unified Model - Wikipedia

The Unified Model is a Numerical Weather Prediction and climate modeling software suite originally developed by the United Kingdom Met Office, and now both used and further developed by many weather-forecasting agencies around the world. The Unified Model gets its name because a single model is used across a range of both timescales (nowcasting to centennial) and spatial scales

EPS forecasts from a single forecast centre only address some of the uncertainties inherent in numerical weather predictions and many other sources such as boundary conditions or numerical implementations exist. For example, model physics and numerics have substantial impact in generating the full spectrum of possible solutions [26].
