    Climate Week Planet Labs event

    3:00pm to 4:00pm

    Location: 

    Seminar Room MCZ, 440

    Speaker: Joseph Mascaro and Andrew Zolli

    Title: “Daily Monitoring of the Land Surface of the Earth”

    Abstract: Planet is an integrated aerospace and data analytics company that operates the largest fleet of Earth-imaging satellites. With more than 140 cube-sats now in orbit, Planet is collecting approximately 50 million square kilometers of imagery per day, or 1/3 of the land surface of the Earth (3-5m per pixel, in red, green, blue and near infrared spectral bands). Later in 2017, Planet’s constellation will image the entire land surface of the Earth on a daily basis. Due to… Read more about Climate Week Planet Labs event

    ClimaTea Journal Club

    3:00pm to 4:00pm

    Location: 

    Seminar Room MCZ, 429

    Speaker: Nathan Mueller

    Nathan will be presenting the paper "Observed changes in extreme wet and dry spells during the South Asian summer monsoon season"

    Here are his thoughts on the paper: 

    "Singh et al. examine changes in mean precipitation, precipitation variability, wet spells, and dry spells during the South Asian summer monsoon season for the years 1951-2011. The authors find that mean precipitation is declining while precipitation variability is increasing. Dry spells are becoming more frequent but less intense, while wet spells are becoming more intense. The… Read more about ClimaTea Journal Club

    ClimaTea Journal Club

    3:00pm to 4:00pm

    Location: 

    Seminar Room MCZ, 440

    Speaker: Colin Meyer

    Colin  will be presenting the paper "Dynamics of ice stream temporal variability: Modes, scales, and hysteresis"

    Here are his thoughts on the paper: 

    "Ice from the interior of continental ice sheets such as Greenland or Antartica primarily drains through fast-flowing, localized features called ice streams. These ice streams are known to turn on and off, known as stagnating and activating. The variability in ice stream discharge from the Hudson Strait ice stream of the Laurentide Ice Sheet is likely mechanism behind Heinrich events,… Read more about ClimaTea Journal Club

    ClimaTea Journal Club

    3:00pm to 4:00pm

    Location: 

    Seminar Room MCZ, 440

    Speaker: Wanying Kang

    Wanying  will be presenting the paper “Seasonal Variability of the Polar Stratospheric Vortex in an Idealized AGCM with Varying Tropospheric Wave Forcing.”

    Here are her thoughts on the paper: Using an idealized atmospheric model with seasonal cycle, they investigated how the polar stratosphere seasonal variability responds to varying topography. Specifically, they focused on the response in  Sudden Stratospheric Warming (SSW) frequency, and the timing of final warmings. K=2 topography is more efficient than k=1 in shifting final warming and changing SSW… Read more about ClimaTea Journal Club

    ClimaTea Journal Club

    3:00pm to 4:00pm

    Location: 

    Seminar Room MCZ, 429

    Speaker: Marena Lin

    Marena will be presenting on the paper  Guo et al. (2015), "Impacts of 20th century aerosol emissions on the South Asian summer monsoon in CMIP5 models:”

    Here are her thoughts on the paper:

    All-India Monsoon Rainfall is estimated to have declined over the second half of the 20th century, with some attributing this primarily to increased anthropogenic GHGs and others to increases in aerosols. Guo et al. (2015) investigate the effects of aerosols, differentiating between the indirect and direct effects, on Indian monsoon rainfall in the CMIP5 models.

    ClimaTea Lecture

    3:00pm to 4:00pm

    Location: 

    Seminar Room MCZ, 440

    Speaker: Professor Dargan Frierson from University of Washington

    Title: "How the sea, land, ice, and mountains move the rain” and he says the following about the talk:

    "I’ll talk about research using idealized GCMs to pick apart the role of various factors in setting the rainfall distribution on Earth, including simple continents, mountain ranges, the ocean circulation, ice sheets, and vegetation. The use of simple diffusive closures in the atmospheric energy… Read more about ClimaTea Lecture
