Using the Weather Research and Forecasting model coupled with a spectral‐bin microphysics (“SBM”) measurements from Atmospheric Radiation Measurement Mobile Facility field campaign in China (AMF‐China), authors examine aerosol indirect effects (AIE) typical cloud regimes of warm cold seasons Southeast China: deep convective clouds (DCC) stratus (SC), respectively. Comparisons two‐moment bulk (“Bulk”) are performed to gain insights for improving schemes estimating AIE weather climate...

Nighttime light (NTL) is a critical indicator of urban vitality and development. Using NTL as representation development, the study explores how different fresh-made beverage shops, namely boba coffee proxy various facets development in four megacities China. Existing studies mostly discuss broad concept seldom investigate diverse represented by indicators. This selects Beijing, Shanghai, Guangzhou, Shenzhen case regions (1) their pattern NTL. (2) heterogeneous spatial distribution shops;...

According to the United Nations, proportion of older population is increasing at a faster rate than all other age groups. Hence, well-being adults mounting concern worldwide in current century. Using single greenery metric, previous studies linked greenness residents' well-being. This study aims extend this field by focusing on mental and physical using remote sensing streetscape metrics evaluating neighborhood greenness. We selected 20 residential neighborhoods Guangzhou City, China as...

Identifying and evaluating polycentric urban spatial structure is essential for understanding optimizing current development. In order to accurately identify the centers of Guangdong–Hong Kong–Macao Greater Bay Area (GBA), this study firstly fused nighttime light data, POI population migration data based on wavelet transform, then identified GBA by carrying out cluster outlier analysis, evaluated level different byconducting geographical weighted regression analysis. Using fusion, we 4579.81...

The rise of mass tourism has encouraged rapid economic growth; meanwhile, the eco-environmental system come under increasing pressure. To achieve sustainable development, it is critical to deeply explore relationship and evolution characteristics between three subsystems: tourism, economy, eco-environment. This study aims develop a more comprehensive indicator for evaluating coupling coordination degree (CCD) tourism-economy-environment (TEE) using statistical data from nine cities in Pearl...

Abstract Urban green spaces play a critical role in regulating air temperature, reducing pollution and enhancing people’s well being. Yet, existing data research on potential drivers of urban space availability Latin America are limited. Here, focusing 371 large cities 11 countries America, we described the total per capita variability space, its spatial configuration parks across categories cities’ natural, built socioeconomic environments. We tested relative importance geographic (climate)...

Abstract. An airborne cloud seeding experiment was conducted over the eastern coast of Zhejiang, China, on 4 September 2016 during a major international event held in Hangzhou. In an attempt to reduce likelihood rainfall onset, for weather modification took place by hygroscopic agents warm clouds droplet size. The effectiveness is examined, mainly stratiform with patchy small convective cells. A radar-domain-index (RDI) algorithm proposed analyze effect. threshold strategy and tracking radar...

Population aging has become one of the most prominent population trends in China and worldwide. Given retirement physical limitation elderly, neighborhood gradually center their daily lives communication. Community cohesion plays an essential role improving elderly’s subjective wellbeing. However, present studies on concept relationship between different dimensions community are mainly western countries. Meanwhile, wellbeing only focused aspect such as interaction. To address this research...

The water in the air is composed of vapor and hydrometeors, which are inseparable global atmosphere. Precipitation basically comes from hydrometeors instead directly vapor, but rarely focused on previous studies. When assessing maximum potential precipitation, it necessary to quantify total amount present within an area for a certain period time. Those that have not participated precipitation formation surface, suspending atmosphere be exploited, defined as cloud resource (CWR). Based budget...

Based on the concepts of cloud water resource (CWR) and related variables proposed in first part this study, paper provides details two methods to quantify CWR. One is diagnostic quantification (CWR-DQ) based satellite observations, precipitation products, atmospheric reanalysis data; other numerical (CWR-NQ) a resolving model developed at Chinese Academy Meteorological Sciences (CAMS). The are applied CWR April August 2017 over North China, results evaluated against all available...

Blue spaces is associated with self-rated health (SRH), but little known about the pathways underlying this association among Chinese urban elderly individuals. Based on neighborhood effect theory, study examined relationship between blue and SRH individuals using data from a questionnaire survey conducted in Guangzhou, remote sensing images, street views, environmental information context of megacity. In addition, multilevel linear model mediating empirical analyses were performed. Results...

By using the diagnostic quantification method for cloud water resource (CWR), three-dimensional (3D) fields of 1° × resolution during 2000–2019 in China are firstly obtained based on NCEP reanalysis data and related satellite data. Then, combined with Global Precipitation Climatology Project (GPCP) products, a gridded CWR dataset recent 20 years is established. On this basis, monthly annual variables its six weather modification operation sub-regions obtained, characteristics different...

In this study, the impact of artificial precipitation enhancement operation on wet scavenging air pollutants is investigated based an aircraft in Yangtze River Delta region China 1 November 2020. Multiple measurement data are used, including regional meteorological and environmental comprehensive field observation at Nanjing University Information Science Technology (NUIST) campus site. The results show that affected areas cover part Anhui Jiangsu provinces. ratio between target contrast...

The transport and dispersion (T&D) of catalyst particles seeded by weather modification aircraft is crucial for assessing their effects. This study investigates the capabilities Chinese geostationary satellite FY-4A identifying physical response cloud seeding with AgI-based catalysts continuously monitoring its evolution a event that occurred on 15 December 2019 in Henan Province, China. Satellite measurements are also used to verify an operational T&D algorithm. results show...
