Heavy rainfall events can cause major disruption to human activities. It is desirable to predict these events ahead of time so that decision makers can take action to protect life, property and prosperity. Nowcasting, or short-term forecasting from observations, remains an important tool in predicting these events. The essential goals of nowcasting are identical to those of all weather forecasting, with the only difference being the spatial and temporal scales involved. The World Meteorological Organization (WMO, 2016) distinguishes among the various forecasting time horizons as: "Usually forecasts for the next 0-2 hours are called nowcasting, from 2-12 hours very short-range forecasting (VSRF), and short-range forecasting beyond that; but the capabilities of the different ranges can vary upon variables and weather situations." Radar-based nowcasting emerged in an era of mainly synoptic and mesoscale weather prediction. Predicting rainfall during that time was a challenge for numerical weather prediction (NWP) models, since computational restrictions limited the resolution at which NWP models could operate. As a result, NWP models were able to capture mesoscale weather patterns such as fronts, but not the smaller-scale convective patterns that occur within mesoscale systems. Thus, these models had limited utility in predicting rainfall in the early hours of the forecast because of its dependence on the unrepresented small scales.
'Pope Simulator' video game lets you live out your papal dreams
Pope Simulator will let you step in to the shoes of one of the most powerful people on Earth to see if you can bring about world peace. Polish publishers, Ultimate Games, haven't set a launch date for the game but have uploaded a preview of the software to Steam and say it is'coming soon'. A new trailer for the game opens with white smoke coming from a chimney, signifying the election of a Pope - likely a cutscene before the game begins with you as the new Pontiff. The stunning trailer gives some insight into how the user will step into papal life and live out the daily duties of the Pope - including prayer and blessings. This is just an illustrative trailer as Ultimate Games have only just started working on the new simulator game - saying it will be some time before it is released.
Which Comes First, the AI or the Business Strategy? - AI Trends
Companies need to align the AI strategy with the business strategy. First the company needs a business strategy. Can the AI help with that? AI is being applied to the model decision-making of governments and corporations. A recent article in Forbes described the Real Time Strategy (RTS) technology involved in Google DeepMind's gaming software that works with "imperfect information."
