        • Monsoon / Precipitation Variability and Predictability - Roxy Mathew Koll, Indian Institute of Tropical Meteorology


          from Kavli Frontiers of Science Added 153 1 0

          Whither the Monsoon? Roxy Mathew Koll, Indian Institute of Tropical Meteorology The South Asian monsoon is one of the strongest phenomenon in the tropical climate system, and affects the lives of over two billion people via its effects on food security, water resources and power generation. Traditionally, monsoon has been defined as the seasonally reversing winds, accompanied by changes in rainfall. During summer, these winds flow southwesterly from the Indian Ocean to South Asia, providing up to 90% of the total annual rainfall. These winds are driven by the differential heating between land and sea, which is dependent on the seasonal migration of solar insolation. Monsoon can be considered as a huge movement of water from the oceans to the landmass. The South Asian monsoon as we see now shaped up when the Indian subcontinent collided with the Eurasian continent about 20-30 million years before. The location of the Indian peninsula in the north Indian Ocean enhanced the land-sea temperature difference, resulting in the monsoon as we see now. Now the term monsoon is used to define similar phases of rainfall accompanying changes in the wind circulation—such as the African, Australian and the American monsoons. The monsoon has a variability on different timescales such as the intraseasonal, seasonal and interannual scales, and exhibits long-term trends too. Despite the advancement of science in understanding the monsoon, its complexity spanning several earth system components, the spatiotemporal variability and teleconnections (e.g.: El Niño) makes it a challenge to comprehend and predict it successfully—the seasonal forecast skill of present day models are at 0.5-0.6 (on a scale of 0-1). Global warming conditions accentuate the need of realistic future projections by climate models, but we are yet to be there as these models do not show a great skill in simulating the present day monsoon. Recent studies suggest that extreme rain/weather events are increasing over the monsoon domain. At the same time, past data indicate that the summer monsoon circulation and rainfall has weakened, due to a rapidly warming Indian Ocean which has reduced the land-sea temperature difference. Whither the monsoon? What will be the fate of the population and biodiversity in view of a monsoon climate which is changing? These are questions which remain, but require immediate attention to!

          • Monsoon / Precipitation Variability and Predictability - Deepti Singh, Stanford University


            from Kavli Frontiers of Science Added 3 1 0

            Historical Trends in the Characteristics of the Indian Summer Monsoon Deepti Singh, Stanford University The Indian Summer Monsoon directly affects the lives of over 1/6th of the world’s population, being critical for agriculture (>50% of the agricultural lands are still rainfed) and water availability in the subcontinent. Agricultural activities across large parts of the subcontinent are heavily dependent on summer monsoon rainfall and are closely tied to the monsoon timing (onset and retreat) and monsoon length. The summer monsoon is characterized by a dominant 30-60 day mode of intraseasonal variability causing the occurrence of wet and dry spells over a substantial portion of India during the peak-monsoon months (July-August). Extreme events associated with such variability during the monsoon season can adversely affect crop yields. Monsoon lows and depressions contribute substantially to the total monsoon and are often associated with heavy rainfall that can disrupt agricultural activities and have high humanitarian costs. My talk will examine historical trends in these aspects of the monsoon that are critical for agricultural planning and management. I will discuss changes that have occurred in the monsoon onset, mean seasonal rainfall, and characteristics of extreme event and monsoon low-pressure systems. This discussion will also highlight the available datasets and methodologies used in these studies. Finally, I will briefly discuss some work on the attribution of these historical events to anthropogenic greenhouse gases and aerosols focusing on recent high-impact extreme events.

                  • Second Avenue - Martha Madison Optics Sample


                    from Second Avenue Learning Added

                    Transform your science curriculum! Introducing four new physical science games (Simple Machines, Optics, Waves, and Forces) from Second Avenue Learning, designed to minimize teacher preparation while maximizing student participation. Also, the fun factor - we maximize that, too. Imagine turning your classroom into an ancient temple, full of optical wonder. Your students can then create, solve, and share their own game levels (Optics). When playing Waves, students can save their animal friends from an impending storm using their knowledge of transverse and longitudinal waves. Forces invites students to play with the penguins, sending ice blocks across a frozen terrain and learning key concepts along the way. In Simple Machines, students play with springs, pulleys, and inclined planes as they solve real science problems. In every level of every game, Martha Madison captivates students, encouraging them to persist in science learning through entertainment-style gameplay. Martha Madison, meerkat scientist and student mentor, leads the narrative of each game, adding helpful scaffolding throughout to keep students on track as they embark on each science-filled problem-solving adventure. The story behind each game is fresh, but our goal is the same: excite students, improve educational outcomes, and address the real needs of students and teachers. Martha Madison games offer students, teachers, families, and administrators measurable results, viewable in a progress dashboard. Each game comes with a full teacher resources package, complete with instructional materials, worksheets, lesson plans, and standards correlation – everything a teacher needs to get started with the games in the classroom. We make it easy—each lesson and game session is designed to fit within the confines of a class period. Backed by research, and built to be fun, all games incorporate best practices in teaching and leverage innovative game design. Simply put, students go bonkers for Martha Madison. Martha Madison is now available for purchase in the Edmodo store! edmodo.com/store/app/martha-madison-forces edmodo.com/store/app/martha-madison-optics edmodo.com/store/app/martha-madison-waves edmodo.com/store/app/martha-madison-simple-machines Want to try before you buy?
