Pantropical response to global warming and the emergence of a La Nina-like mean state trend

During the past century, the tropical Pacific Ocean has warmed significantly less than the other tropical oceans  in response to increasing greenhouse gases (GHGs). This La Nina-like warming trend in the observations is in stark contrast to the El Nino-like warming trend projected by the Coupled Model Intercomparison Project (CMIP) models for both the 20th...

Why does the upper atmosphere cool with increasing carbon dioxide?

According to model simulations with increasing carbon dioxide in the atmosphere, the zonal mean temperature in the atmosphere get warmer in the troposphere (< 10km or > 100hPa) and colder in the stratosphere (10 ~ 50km or 100 ~ 1hPa). A simple explanation is that the amount of infrared heat radiated out to the space... Continue Reading →

NOAA CPC's current ENSO alert system status is El Nino Watch: ENSO-neutral is favored through Northern Hemisphere summer 2018, with the chance for El Niño increasing to 50% during fall, and ~65% during winter 2018-19. http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.shtml https://www.climate.gov/news-features/blogs/enso/june-2018-enso-update-el-ni%C3%B1o-watch  

June 2, 2018 – Preliminary data from NOAA’s Storm Prediction Center indicate that the U.S. had a record low number of tornadoes

The spring severe weather season for the U.S. (March - May) is finally over. We had 449 EF0 - EF5 tornadoes from Jan 1 to June 2, which is a record low number for the period and certainly well below the historical average during 2005 - 2015 (792). Recent studies have suggested that U.S. tornado... Continue Reading →

May 24, 2018 – NOAA’s Climate Prediction Center predict a near- or above-normal 2018 Atlantic hurricane season

NOAA’s forecasters predict a 70-percent likelihood of 10 to 16 named storms (winds of 39 mph or higher), of which 5 to 9 could become hurricanes (winds of 74 mph or higher), including 1 to 4 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). An average hurricane season produces 12 named storms,... Continue Reading →
