Hydrologie : bilan de la période de recharge des nappes
20 April 2015

La période de recharge (septembre à mars) des nappes vient de s'achever. Après deux années consécutives excédentaires (à hauteur de 15 à 20 %), le bilan pluviométrique sur cette période est, cette année, proche de la normale mais contrasté géographiquement. Du pourtour méditerranéen à l'Ardèche ainsi qu'en Haute-Corse, l'excédent est souvent compris entre 20 et 50 %. En revanche, le déficit atteint localement 30 % en Savoie et Haute-Savoie ainsi que des Deux-Sèvres à la Sarthe.

Les précipitations depuis septembre 2014 ont toutefois permis une recharge des nappes souterraines satisfaisante sur l'ensemble du pays.

Risk of moderate flooding for parts of central and eastern United States
20 April 2015

According to NOAA’s Spring Outlook released today, rivers in western New York and eastern New England have the greatest risk of spring flooding in part because of heavy snowpack coupled with possible spring rain. Meanwhile, widespread drought conditions are expected to persist in California, Nevada, and Oregon this spring as the dry season begins.

“Periods of record warmth in the West and not enough precipitation during the rainy season cut short drought-relief in California this winter and prospects for above average temperatures this spring may make the situation worse,” said Jon Gottschalck, chief, Operational Prediction Branch, NOAA’s Climate Prediction Center.

Special Climate Statement 51 – an exceptional autumn hot spell in norther n and central Australia
20 April 2015

An exceptional hot spell for the time of year affected large parts of northern and central Australia during March 2015. Initially, the heat was significant but relatively localised, mostly confined to the Top End and Gulf Country in the Northern Territory and adjacent areas of far northwest Queensland. From mid-March onwards, the heat extended over a much larger area. It peaked on 19 and 20 March when records were set over large parts of the Northern Territory and Queensland, as well as outback South Australia and northern New South Wales. Many records were set during this hot spell. The Northern Territory and Queensland had their hottest March days on record in area-averaged terms, whilst the event also included the highest temperature ever observed in Australia in the second half of March.
