This study was conducted to examine the climate characteristic of southern highland Tanzania (Latitude 6°S-12°S and Longitude 29°E-38°E). The findings reveal that rainfall over region is linked with SST Indian Ocean, where warmer (cooler) western Ocean accompanied by high (low) amount Tanzania. During wet (dry) years, weaker (stronger) equatorial westerlies anticyclone (cyclonic) anomaly tropics act reduce (enhance) export moisture away from East Africa. wettest (driest) season found be...
This study sought to establish the effectiveness of water washing pre-treatment on quality municipal solid waste incineration (MSWI) fly ash (FA) for reuse and solidification or stabilization (S/S). Initial analysis FA sample shows that it did not meet USEPA-1311 toxicity characteristic leaching procedure (TCLP) regulatory limits 2011. As a result, two-stage process was carried out an attempt improve MSWI FA. After pre-treatment, heavy metals in met limits, thereby making non-toxic safe...
In this study, we investigated six air pollutants from 21 monitoring stations scattered throughout Wuhan city by analyzing meteorological variables in the atmospheric boundary layer (ABL) and mass backward trajectories HYSPLIT during pollution events. Together with this, ground were also used investigation period: 1 December 2015 to 30 November 2016. Analysis results period show that was polluted winter PM2.5 (particulate matter aerodynamics of less than 2.5 microns) summer ozone (O3). The...
Measurement of PM2.5 concentration, dry and wet deposition water-soluble inorganic ions (WSII) their flux was carried out. During sampling, a total number 31 samples PM2.5, five seven were collected. The analyses results showed that the average concentration 122.95 µg/m3 whilst WSII 51.63 µg/m3, equivalent to 42% mass PM2.5. correlation coefficients between in significant (r = 0.50 p-value 0.0019). Ions SO 4 2 − , NO 3 Cl NH + dominant entire (PM2.5, depositions), nevertheless, both below...
Abstract A previous study found that the September–October (SO) Antarctic Oscillation (AAO) shows an out‐of‐phase variation of late January–February (JF) wet and cold weather (wet–cold) in southern China. This explored underlying mechanism sea ice may be responsible partially for such a relationship. The SO AAO stimulates sea‐ice dipole pattern (ADP) anomalies, which induce anomalous convective precipitation Inter‐Tropical Convergence Zone (ITCZ) Latin America‐Atlantic (LAA) Western Pacific...
Ambient air quality monitoring data and radar tracking sonde were used to study the atmospheric boundary layer structure (ABLS) its changing characteristics over Wuhan. The index (BLSI), which can effectively describe ABLS, was accordingly developed ability near-surface analyzed. results be summarized as follows. (1) An analysis of ABLS during seriously polluted cases revealed that usually dry warm with a small ventilation (VI); meanwhile, clean wet cold large VI. (2) correlation between...
Tanzania enacted the Environmental Management Act (EMA) in 2004 with Impact Assessment (EIA) as one of its major tools for protecting environment from impacts development projects.According to EMA, all new projects have undertake EIA before they are commissioned.This paper assesses what extent this has been achieved.The study involved 5 industries (as cases) which Certificates, staff National Environment Council (NEMC) is responsible enforce Municipal Councils, Wards, Registered Consulting...
Abstract Based on the Empirical Orthogonal Functions decomposition of Sea level pressure (SLP) anomalies over southern extratropic, second pattern is defined as a mode (SMD 2 ), and its corresponding principal component named index. The most significant feature SMD seesaw SLP, which indicates opposite phase Amundsen Low surroundings. spatial EOF2 varies in different months but March similar to . This study shows that negatively associated with June precipitation China. mechanisms can be...

Abstract This study investigates the interannual cross‐seasonal association between winter energetic particle precipitation, which is related to geomagnetic activity (GA), and southern annular mode (SAM) in following summer by employing ERA5 reanalysis dataset. The results reveal a marked negative correlation these variables on an timescale. Therefore, we analyse GA signatures atmosphere find that evolution of SAM phase driven may be caused two mechanisms: First, for high levels, middle...
<p>The Antarctic Oscillation (AAO) is the dominant mode of southern extratropical atmospheric mass variability which has potential influences on Northern Hemisphere (NH). This study reveals a significantly negative correlation between September-October (SO) AAO index and occurrence rate following January-February (JF) wet cold weather in Middle Lower Reaches Yangtze River Basin (MLRY) China. The latter quantified by Precipitation-Temperature (PT) Index. JF PT modulated both...
