series of Niño3.4 indices for all initialised forecasts relative to ERSST IV. Prediction of Regional Impacts Based on Nov0 initialised forecasts: Model predicts overall dry conditions across Australia during 1 st (Y0) and 2 nd (Y+1) wet-season of multi-year El Nino events but underestimates the rainfall

/maproom/. Additional Information: ^Note: In March western Nigeria had normal rainfall but it was Very Wet in the east, whilst the dry season continued in the north. ^^Note: In April, northern Nigeria was Very Wet and western Cameroon Very Dry. * Region usually experiences less than 10mm/month

resilience of vulnerable communities around the world since 2014. Through the WCSSP programme, we are working collaboratively on projects that focus on the global challenges of weather and climate with partners in Brazil, China, India, South Africa and Southeast Asia. International collaboration

equinox marks the start of spring, and the autumn equinox marks the start of autumn. Do all countries have the same seasons? Not all parts of the world experience four seasons. Countries near the equator often have just two - wet and dry - because the Sun’s position doesn’t change much throughout

the month (dry season). Additional Information: (1) Note: Normal or cold in the north, hot in the south (2) Note: Normal in the northeast (3) Note: Large variations across the country (4) Note: Warm or hot in the southwest, cool to normal in the northeast (5) Note: Normal in the west, very wet

Kenya, western Tanzania and parts of Malawi and Zambia were wetter than normal, with more mixed conditions in December. 3-Month Outlook February to April - Rainfall Outlook: The development of La Niña usually increases slightly the chance of a wetter than normal season across parts of southern Africa

to prolonged periods of rainfall. If the winds continue to converge, wet conditions can persist, sometimes resulting in significant rainfall totals and even flooding. Convergence lines are not limited to a particular season and can occur at any time of year. During the summer months, local sea
