An improved typhoon simulation method based on Latin hypercube sampling method.

In order to further improve the prediction accuracy of typhoon simulation method for extreme wind speed in typhoon prone areas, an improved typhoon simulation method is proposed by introducing the Latin hypercube sampling method into the traditional typhoon simulation method. In this paper, the improved typhoon simulation method is first given a detailed introduction. Then, this method is applied to the prediction of extreme wind speeds under various return periods in Hong Kong.

[Gaseous Nitrogen Emission from Soil After Application of NH-N Loaded Biochar].

To safely and effectively transfer NH-N from eutrophic water to soil, biochar was applied to adsorb NH-N from wastewater, and this NH-N loaded biochar (N-BC) was subsequently used as a soil amendment. Understanding the influence of N-BC on NO-N emission and NH-N volatilization is important for both decreasing the application of chemical fertilizers and reducing gaseous nitrogen loss from soil. In this study, experiments were conducted in soil columns with four treatments, namely CK (no fertilizer), NPK (chemical fertilizer), N-BC+PK (NH-N loaded biochar+chemical fertilizer), and BC+NPK (biochar+chemical fertilizer).
