A soil-derived dust emission scheme has been designed to provide an explicit representation of the desert dust sources for the atmospheric transport models dealing with the simulation of the desert dust cycle. Two major factors characterizing the erodible surface are considered: (1) the size distribution of the erodible loose particles of the soil which controls the erosion threshold and the emission strength and (2) the surface roughness which imposes the efficient wind friction velocity… 

An improved dust emission model – Part 1: Model description and comparison against measurements

Abstract. Simulations of the dust cycle and its interactions with the changing Earth system are hindered by the empirical nature of dust emission parameterizations in weather and climate models. Here

A new dust cycle model with dynamic vegetation: LPJ-dust version 1.0

Abstract. This paper presents a new offline dust cycle model which uses the Lund-Potsdam-Jena dynamic global vegetation model (Sitch et al., 2003) to calculate time varying dust sources. Surface

The influence of simulated surface dust lofting and atmospheric loading on radiative forcing

Abstract. This high-resolution numerical modeling study investigates the potential range of impact of surface-lofted dust aerosols on the mean radiative fluxes and temperature changes associated with

A mesoscale model study of the seasonal dust activity in the semiarid drylands of Central Asia, focusing on the effects of wind speed, soil moisture, surface roughness heterogeneity, and vegetation phenology on the threshold friction velocity (u*t) and dust emission during the dust season of 1 March to 31 October 2001.

Numerical simulation for a wind dust event in the US/Mexico border region

Soil-derived dust represents one of the major components of the natural atmospheric aerosols. Arid and semiarid areas with unpaved and non-vegetated land cover are particularly vulnerable to

Development of a New Wind-Blown-Dust Emission Module Using Comparative Assessment of Existing Dust Models

A new wind-blown dust emission module has been fabricated to be used in investigating the development and transport of Asian dust storms. A number of different dust emission models currently used

Dust Production Mechanisms

This chapter is concerned with dust production mechanisms, that is, the interactions between the wind and the surface that lead to the emission of fine soil particles. Mineral dust emissions mainly

Stochastic parameterization of dust emission and application to convective atmospheric conditions

Abstract. We develop a parameterization scheme of convective dust emission for regional and global atmospheric models. Convective dust emission occurs in the absence of saltation as large eddies

An improved dust emission model – Part 2: Evaluation in the Community Earth System Model, with implications for the use of dust source functions

Abstract. The complex nature of mineral dust aerosol emission makes it a difficult process to represent accurately in weather and climate models. Indeed, results in the companion paper indicate that

Effect of Saltation Bombardment on the Entrainment of Dust by Wind

Saltation is the wind-driven, hopping motion of sand-sized particles across an erodible surface. This mode of motion not only transports sand and similar materials in its own right but can also
