La Nia will not be the only meteorological force at play that could shape the weather patterns across the U.S. during the upcoming winter. Since 1900, this has only happened 4 times. Lets dig a little deeper and look at some of the characteristics within these two convective phases (Figure 3). Every winter in the south brings swings from warm days to cold days with chances for snow, ice, and severe weather in between. Pastelok added that unlike volcanic ash, which reflects sunlight, the water vapor acts like a blanket and keeps warmer air trapped underneath. December-February: January-March: For the MJO to be considered active, this dipole of enhanced/suppressed convective phases must be present and shifting eastward with time. Precipitation tends to be below-average across the southern tier of the United States and wetter than average across the Pacific Northwest and Ohio Valley.

Expect numerous chances for cold fronts, some with rain, some with snow and ice. (1) The terciles, technically, are the 33.33 and 66.67 percentile positions in the distribution. Widespread extreme drought continues to persist across much of the West, the Great Basin, and the central-to-southern Great Plains. . The effects are usually strongest in Northern Hemisphere winter. However, tornado and severe weather activity is more variable (noisier and harder to predict) than ordinary weather (think temperature and precipitation), and any ENSO signal is harder to see. These two phases produce opposite changes in clouds and rainfall and this entiredipole(i.e., having two main opposing centers of action) propagates eastward. Arkansas is such a beautiful place to hike, and the landscape of the Natural State during the winter months is extra enchanting. Atmospheric angular momentum is related to ENSO and also shows the impact of tropical forcing on tornado activity (Gensini and Marinaro, 2016). 5].
