Abstract
The total area with 24 hrs precipitation has shrunk by 7% between 50°S–50°N over the period 1998–2016, according to the satellite-based Tropical Rain Measurement Mission data. A decrease in the daily precipitation area is an indication of profound changes in the hydrological cycle, where the global rate of precipitation is balanced by the global rate of evaporation. This decrease was accompanied by increases in total precipitation, evaporation, and wet-day mean precipitation. If these trends are real, then they suggest increased drought frequencies and more intense rainfall. Satellite records, however, may be inhomogeneous because they are synthesised from a number of individual missions with improved technology over time. A linear dependency was also found between the global mean temperature and the 50°S–50°N daily precipitation area with a slope value of −17 × 106 km 2∕°C. This dependency was used with climate model simulations to make future projections which suggested a continued decrease that will strengthen in the future. The precipitation area evolves differently when the precipitation is accumulated over short and long time scales, however, and there has been a slight increase in the monthly precipitation area while the daily precipitation area decreased. An increase on monthly scale may indicate more pronounced variations in the rainfall patterns due to migrating rain-producing phenomena.

so what you see here and the interested in prison fish are unlock the scenery fold there are some obvious explanations we a whole new moisture the rate of evaporation from the surface increases with higher temperatures the colors become taller but can also be some other explanations the hydrological
cycle works like a funnel there is a continuous in operation taking place over larger areas such as the oceans the evaporation Lozier with moisture but the moisture out of the atmosphere is not changing much on average and the rain removes the moisture added but it doesn't rain everywhere where all

Oresme border regions by how much is the ring concentrators how
much is the rainfall rate and modified by the differences in the area of
evaporation and in the area of rain and how can I couldn't quantify there
is some data that can give me an answer the

measurements goes back to 1998 on a daily basis these data suggest that invariance over 25 per cent of the area applying an amplification of rates by a factor of between 2 and 3 when the evaporation increases when I started rainfall measurements from the I found an unexpected traits in that satellite data the area was daily decreased by 7 per cent upon in 99 and and conciseness 16 a decrease in the area of precipitation applies even stronger amplification of the rainfall intensity making their way more concentrated on a smaller area it also suggests more drought conditions as the the with rain is reduced I analyzed how the change in the area of daily range varies with a global mean temperature and find a connection a reduction of 17 million square kilometer per degree centigrade warming in this connection is real and objections 14 thousand 100 may indicate our party 8 % reduction in the data in Valerian given the emissions in
