Annual precipitation is 469.9 mm, with highest rainfall occurring November to March, coupled with extremely low precipitation occurring between June to August. climate classification, the formalization of systems that recognize, clarify, and simplify climatic similarities and differences between geographic areas in order to enhance the scientific understanding of climates. These services provide tailored, comprehensive support to help address the unique challenges and vulnerabilities created by regional weather and climate conditions. Mean annual temperature for South Africa as a whole is 17.5℃, with average monthly temperatures ranging between 22☌ (December, January) and 11☌ (June, July). NCEI’s Regional Climate Services provides access to climate information, products, and other resources for specific regions across the United States. The high evaporation rate of already dry soils and the virtual absence of permanent surface water over large parts of the country make water is a scarce resource, with some projections indicating that even without climate change, the country is likely to run through its existing surface water resources. South Africa is highly vulnerable to climate variability and change due to the country’s high dependence on rain-fed agriculture and natural resources. Average temperatures in South Africa range from 15℃ to 36℃ in the summer and -2℃ to 26℃ in the winter. Average annual rainfall in South Africa is about 464 mm, with the Western Cape getting the majority of its rainfall in winter (June to August) and the rest of the country receiving summer (December to February) rainfall. South Africa has both sub-tropical and temperate climate conditions, which are influenced by the ocean along the east and west coasts as well as the interior plateaus, bringing a cool, wet climate in the Drakensberg region, to warm, sub-tropical in the north east, and a Mediterranean climate in the south west and a warm dry desert environment in the central west and north west. The topography varies from desert to semi-desert in the drier northwestern region to sub-humid and wet along the country’s eastern coast approximately half of the country is classified as arid or semi-arid. Approximately 50% of the country’s water supplies are used by the extensive and industrial agriculture sector. The country is located within what is considered a ‘drought belt’ and is the fifth most water scarce country in sub-Saharan Africa. This page presents Nepals climate context for the current climatology, 1991-2020, derived from observed, historical data. Moreover, latitudinal similarities in the distribution offer potential in identifying candidate locations for reciprocal transfer of knowledge on environmental design and operation.South Africa is comprised of a large central plateau that is home to extensive grasslands, a continuous escarpment of mountain ranges that surround the plateau on the west, south and east, and a narrow strip of low-lying land along the coastline. Variations in temperature exist, even between closely spaced sites – emphasizing the need to use location-specific data for enhancing the accuracy of the weather-related analysis. Observed trends agree with conventional wisdom however, sparse coverage in populated areas such as Africa and Asia diminish the versatility of the database. ![]() Identified spatial variability illustrate the effects of latitude, elevation, landuse and nearest coastline. ![]() This research explored geospatial distributions of key HOF (2009) climatic parameters: temperature (dry-bulb, wet-bulb, dew-point and mean) and degree-days at various temporal scales. ![]() Over the years, the program grew to include six regional climate centers that span the U.S. ASHRAE-HOF is the most widely used climatic design conditions database for building energy and HVAC professionals but gap exists in literature on the geospatial and temporal distributions of the HOF dataset. The Regional Climate Center (RCC) Program is celebrating its 40th anniversary While its roots trace back to 1978, the program was greenlit in 1983 and the Northeast Regional Climate Center (NRCC) at Cornell University was officially created. With so many of the renewable energy sources being significantly dependent on weather, it is essential that the temporal and geospatial variability and distribution of climatic design parameters are investigated for effective planning and operation. Mean wind speed data (average wind speeds are taken over the 10 minute period preceding each hour) are available for several sites in Auckland, and these. Understanding the climate and location aspects are usually the first step in energy applications – from buildings to renewable energy. The annual average temperature in the region is 22 to 26 C (72 to 79 F), with not much variation between the warmest and the coldest months.
