Understanding and characterising climate change at a small scale is fundamental to face its impacts on local vulnerabilities and development projects. This study characterises climate parameters in the southern part of Côte d’Ivoire, more specifically in Bingerville and La Mé localities. Several methods were used to carry out the study, they include Nicholson’s rainfall index, Gumbel’s law and De Martonne’s aridity index. The results show that the climate in this region has been subject to ...

Drought frequency has increased worldwide in recent years due to global warming, causing famine, water shortage, and economic loss. This paper aimed to assess the meteorological drought in Algeria, using two globally accepted drought indices, Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI). The SPI and SPEI at 3-, 6-, 9-, and 12-month timescale were obtained to analyze the temporal variability of different drought levels. Pearson correlation ...

Increasing airborne particulate matter (PM) concentration in Kenya is an unfortunate consequence of rapid urbanization, coupled with a lack of strict implementation of air quality regulations. This has led to detrimental effects on human health, environment and local climate. To gain an indepth understanding of these effects, there is a need for a detailed characterization of PM in terms of abundance, sources, and properties, especially over the less characterized areas such as The Republic of K...

To explore the interannual variability and spatial distribution of extreme precipitation events on the Qinghai-Xizang Plateau, this study employs percentile threshold methods to determine extreme precipitation thresholds based on three-hourly weather data from 215 meteorological stations on the Qinghai-Xizang Plateau. Additionally, extreme precipitation indices are calculated, and their spatial distribution characteristics are investigated. The main findings are as follows: 1) From 2005-2020, th...

Aerosol optical depth (AOD) and Ångström Exponent (AE) have become the most crucial metrics in assessing climate change. Despite this, studies related to AOD and AE are rare in Kenya. Using Moderate Resolution Imaging Spectroradiometer (MODIS) data, the present study analysed the spatial and temporal variations of aerosol optical depth at 550 nm (AOD 550) and examined the impact of these variations on AE over eight selected towns in Kenya during 2001-2021. The findings indica...

This study utilizes hourly temperature data from the China Meteorological Administration to assess extreme temperatures on the Qinghai-Xizang Plateau. The annual and seasonal variations of extreme temperatures from 2005 to 2020 are analyzed using methods such as the climate tendency rate, T-test, and Mann-Kendall mutation test. Additionally, the study explores the impact of meteorological factors on sudden changes in extreme temperature indices. The results show that the frequency of warm weathe...

In the global context of addressing climate change, carbon neutrality has become a common goal for countries worldwide. Carbon neutrality is not only a key measure for achieving sustainable development but also an important pathway for reducing greenhouse gas emissions and combating climate change. However, the current curriculum content and teaching methods in pollution meteorology do not adequately reflect the latest requirements and developments related to carbon neutrality, making curriculum...

Climate change is the most dangerous threat facing the world. This article analyzed near-future trends and changes in rainfall, temperature and wind speed over highlands and lowlands of Burundi, and their potential effects on water and electrical energy availability. Observed and gridded data were considered over the period 1981-2020 while forecasts from eight selected CMIP6 models were used over the period 2021-2045. A modified Mann-Kendall’s test was used to detect trends while Pettitt’s test ...

The atmospheric sounding experiment is a practical course that complements the theoretical course of atmospheric detection. Mastering the basic experi-mental techniques of atmospheric detection is a fundamental requirement for the development of talents in atmospheric science and atmospheric detection for the new era of meteorological observation. The School of Atmospheric Sciences at the Chengdu University of Information Technology has adjusted the teaching content and system of the traditional...

The discovery and exploitation of crude oil in the Niger Delta Region of Nigeria by the various Petroleum Companies have greatly enhanced the nation’s economy. However, practices linked to their discovery, growth and production operations have important and detrimental local effects on the ambient atmosphere. A good understanding and quantification of the concentrations of the greenhouse gases in this region including those of CO 2, CH 4, O 3 and NO 2 as a...
