Weather Tips - What is El Niño?

El Niño. We hear it being brought up in the news quite a bit, but what does it actually mean? No, it's not a type of yoghurt!

Although El Niño is forecast to continue during the upcoming three-month period, it may weaken later in 2019. Winter temperatures are forecast to be above average in the east of the South Island and to be above average or near average in all remaining regions.
Grant Dalton, CEO of Emirates Team New Zealand, and NIWA CEO John Morgan recently signed an agreement that will see NIWA’s scientists working closely with Emirates Team New Zealand over the next few years.
A weak, central Pacific El Niño continued during April, as patterns of enhanced rainfall persisted in the vicinity of the International Dateline. More westerly quarter winds than normal. Tasman Sea surface temperatures may influence several spells of unseasonable warmth through the season, particularly in eastern areas, contributed to by frequent westerly air flows.
Dry for most locations, drought for upper South Island
Weather and climate experts from around the world are meeting in Wellington next week to discuss the critical need for accurate forecasting to cope with a changing climate.
A central Pacific El Niño is now occurring as the ocean and atmosphere have been weakly coupled for a third consecutive month. Traditionally, this occurs farther east toward South America and during the early summer season. Mean temperatures are forecast to be above average for all of New Zealand.
Across the North Island, soil moisture levels decreased nearly everywhere during the past week. In the South Island, soil moisture levels decreased during the past week with meagre rainfall in the north and east.
New Zealand’s 3rd warmest January on record.
NIWA has crunched the data on this week’s heatwave and come up with the following record breakers
A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Regions experiencing these soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.
The atmospheric circulation around New Zealand is forecast to be characterised by pressures slightly higher than normal over and to the north of the country. For New Zealand, this pressure pattern will be accompanied by weak south-westerly quarter flow anomalies.
