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 year. In contrast

balanced (Climatological Odds). This wet signal extends into northern Mozambique. Otherwise, much of southern Africa is more likely to be drier than normal, although in absolute terms the potential rainfall deficit is likely to be small as this is towards the end of the dry season. Tropical cyclones

from 1910 across East Anglia and south-east England. It was also the driest spring since 1893 in the England and Wales precipitation series (HadEWP). Some locations recorded less than 25 mm of rain for the whole season. Summer 2011 was rather indifferent and wetter than average for the UK overall

this is more difficult, increasing health risk to humans. Analysis of the new data has shown that global annual / seasonal mean of maximum daily wet bulb temperature, a measure of humidity, has increased by around 0.2°C each decade between 1973-2022. This rate of change is even higher when looking

and Burkina Faso were wet or very wet. Uganda was also very wet in July and August with Cameroon wet in July and very dry in August. Ghana was very dry in July. 3-Month Outlook November to January - Rainfall Outlook: In East Africa, the ‘Short Rains’ season takes place for many parts during this period

Seasonal to decadal forecasts Although climate is expected to warm over the coming century in response to increasing levels of greenhouse gases, regional changes over the coming seasons to a decade or more are likely to be dominated by unforced natural variability of the climate system. Some

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

increase is observed in tropical regions of South America, Northern Africa and through Asia. Similarly, the number of warm nights in these regions have increased by over eight days per decade, leading to a doubling since the late 1970s.  The variability of rainfall over space and time tends to be greater

. Shifting rainfall patterns will likely lead to some regions becoming wetter and others becoming drier. Additionally, these more arid regions could dry further because of global warming. Warmer temperatures can increase evaporation of water from the ground. As soils become drier, the air above may heat
