for the onset of the southwest monsoon begins during the pre-monsoon season from March to May, when rapid solar heating takes place over the land compared to the adjacent oceans, increasing the land-sea temperature gradient. The surface pressure over the land decreases with a trough of low pressure
Global Outlook – Rainfall Climate Outlook Asia: July to April Asia Current Status and Outlook - Temperature Current Status: Warm or hot conditions have dominated over the past three months, although parts of India, Pakistan and China have been nearer normal or cool at times. Cooler conditions extended
normal temperatures in December. Otherwise, above normal temperatures were experienced for most other areas. Outlook: Warmer than normal conditions are much more likely across much of the continent over the next three months. The exception is across parts of Vietnam, Cambodia, Laos, Thailand, where
Whilst the southern half of the UK experiences pulses of heavy rain over the next few days, sunnier skies further north will allow temperatures to rise well above average in places. 25 or 26°C is likely from central to northwest parts of the UK on Friday, and similar values are possible in western

Michael's research currently focuses on multi-year changes of rainfall over the Sahel. The aim of his work is improved understanding why
of different emissions scenarios using the outputs of a global climate model, i.e. RCP 8.5 and now also RCP 2.6. Note that RCP 2.6 is also available over the UK for the Derived Projections, which were produced using a statistical approach (see Derived Projections factsheet for more details). See question
shaped by a dynamic jet stream. Was there a Supercell over the weekend? So, did the UK experience a supercell thunderstorm? The answer, in fact, is yes, at least one storm bore the hallmarks of a supercell, and possibly more. Supercells are the most organised and long-lived type of thunderstorm
