La Nina Rainfall South Africa

The rains have improved soil moisture primarily in KwaZulu-Natal the central and northern Eastern Cape eastern Free State and parts of Mpumalanga which helped accelerate. In South East Asia higher than normal rainfall tends to occur during a La Niña episode which may result in an increased occurrence of floods.

In southern Africa La Niña tends to be associated with above-average rainfall although initial model forecasts suggest that precipitation will be near average for OctoberDecember.

La nina rainfall south africa. Starting in mid-December South Sudan Somalia Ethiopia Kenya Tanzania Rwanda and Uganda are likely to suffer from below average rainfall as a result of a strong La Niña which could result in millions more people going hungry in 2021. La Niña could also lead to increased rainfall in southern Africa WMO said. La Niña ordinarily lasts between 6 and 24 months.

The South African Weather Service SAWS will continue to monitor and provide updates. The impact of ENSO on South Africa. South Africa the continents largest producer of corn is expected to see steady growth in production next year as above-average rainfall due to La Niña is anticipated during the growing season.

Long Term ECMWF model data. La Nina appears to have the greatest influence on rainfall in southern Africa and wet episodes tend to occur throughout the subcontinent during the first few months of the post-La Nina year. These changes can lead to a wide range of impactsboth good and badon agricultural production water availability disease outbreaks fisheries catches and more.

El Niño and La Niña can significantly alter seasonal climate conditions such as temperature and rainfall patterns in many parts of the world. Developing countries are especially. Southeast Asia some Pacific Islands and the northern region of South America are expected to receive above-average rainfall.

La nina 2020 impacts summary the latest seasonal forecasts indicate that the greater horn of africa below normal rainfall central asia below normal rainfall and south east asia some of the pacific islands and the northern region of south america above normal rainfall will see some of the most significant precipitation anomalies. Areas now experiencing drought are likely to face flooding and areas that have seen excessive rainfall are likely to experience drought. The El Niño influence on rainfall over southern Africa occurs largely because of a weakening of tropical convection over the subcontinent.

However they warn that the La Niña the girl in Spanish could also bring the risk of widespread flooding to southern Africa and cause diseases and pests for the livestock industry. Although the southern part of Africa generally receives below-normal rainfall during El Nino years and La Nina usually brings normal or above-normal rainfall it cannot be accepted as a rule. Southern Africa can be divided into numerous rainfall regions each region having a different correlation with ENSO.

A warming of the Indian Ocean during El Niño events appears to be important in providing a teleconnection from the equatorial Pacific Ocean. What does it mean for South Africa. This was indicated by some recent seasonal forecast models it added.

October itself actually produced below-normal rainfall but with La Niña-induced higher rainfall set to begin in November there have already been good showers in most regions of the country. Purchases sentiments are echoed by two weather experts who believe that the La Niña weather will bring heavy rainfall across the summer rainfall regions of Southern Africa. La Niña causes opposite conditions to those associated with El Niño.

La Niña cycles tend to bring above-normal rainfall over the summer rainfall areas of SA. Whereas the impact of El Niño La Niña Southern Oscillation on the rainfall and vegetation greenness of South Africas summer rainfall region is largely documented and still regularly investigated little is known about its impact on the winter rainfall region located at the southwestern tip of the country. Both El Niño and La Niña affect patterns of rainfall atmospheric pressure and global atmospheric circulation and it is associated with rainier-than-normal conditions over southeastern Africa and northern Brazil.

There is a somewhat weaker tendency for below-normal rainfall in eastern equatorial Africa at this time. Whereas the south-western half which falls outside the parts which receive summer rainfall is mostly expected to receive below-normal rainfall Above-normal minimum and maximum temperatures are expected across the country. La Nina appears to have the greatest influence on rainfall in southern Africa and wet episodes tend to occur throughout the subcontinent during the first few months of the post-La Nina year.

La Niña could also affect the South West Indian Ocean Tropical Cyclone season reducing the intensity. The La Niña phenomenon is the reverse of the El Niño where cooler waters develop over the Eastern Tropical Pacific Ocean along the coast of South America. There is a somewhat weaker tendency for below-normal.

La Nina appears to have the greatest influence on rainfall in southern Africa and wet episodes tend to occur throughout the subcontinent during the first few months of the post-La Nina year. Taking into account oceanic and atmospheric factors and the La Niña occurrence the bulk of the Southern Africa region is expected to experience above-average rainfall in. Nothing is guaranteed and climate models are merely a guideline for our complex climate in South Africa.

South Africa produced its second-biggest corn crop on record of 154 million tonnes in 201920 driven by greater acreage and near-record yields.
