High yield synthesis of trans-[(Me(3)P)(OC)(3)Fe = BDur] (Dur, "Duryl" = 2,3,4,6-Me(4)C(6)H) is achieved by salt elimination and subsequent liberation of trimethylsilylbromide from K[Fe(CO)(3)(PMe(3))SiMe(3)] and Br(2)BDur.

Gymnocarpos przewalskii is a rare Tertiary relict species, mainly distributed in desert areas of northwestern China. Changes rainfall have significant impact on the physiological characteristics plants. In present study, effects five simulated levels gas exchange parameters, chlorophyll fluorescence characteristics, and antioxidant system G. were studied. The results show that with increased ne...

Understanding rainfall variability, shifts and trends is of primary importance when considering the potential for biophysical, social and economic impacts. An increase in mean rainfall could enhance agricultural production and water supply. However, if this increase is associated with more extreme rainfall events, it can enhance flood frequency and intensity. Conversely, decreases in mean rainf...

This chapter also focusesaddresses on precipitation intensity measurements (in particular rate of rainfall or rainfall intensity) due to their rapidly increased need for the interpretation of rainfall patterns, rainfall event modeling and forecasts, everyday meteorological and engineering applications, the investigation of evolving events at the local to regional scale with potential tremendous...

Correlation in space between seasonality of malaria and seasonality of rainfall was studied in Sri Lanka. A simple seasonality index was developed by making use of the bimodal seasonality of both malaria and rainfall. The malaria seasonality index was regressed against the rainfall seasonality index taking spatial autocorrelation into account. Despite the presence of spatial autocorrelation, th...

Rainfall data are often collected at coarser spatial scales than required for input into hydrology and agricultural models. We therefore describe a spatio-temporal model which allows multiple imputation of rainfall at fine spatial resolutions, with a realistic dependence structure in both space and time and with the total rainfall at the coarse scale consistent with that observed. The method in...

The issues of downscaling the results from global climate models (GCMs) to a scale relevant for hydrological impact studies are examined. GCM outputs, typically at a spatial resolution of around 3° latitude and 4° longitude, are currently not considered reliable at time scales shorter than 1 month. Continuous rainfall-runoff modelling for flood regime assessment requires input at the daily or e...

[1] Intense storms with high-intensity, long-duration rainfall have great potential to trigger rapidly moving landslides, resulting in casualties and property damage across the world. In recent years, through the availability of remotely sensed datasets, it has become possible to conduct global-scale landslide hazard assessment. This paper evaluates the potential of the real-time NASA TRMMbased...

For more information/comments, please contact: [email protected] INTRODUCTION The Agro-meteorology bulletin is a report produced monthly to report on the agricultural season in Southern Sudan. The emphasis of the report is mainly on rainfall performance and its implication on crops and rangeland. The impact of agricultural season has huge implications on food security situation of household...
