How stratospheric warming and a +AAO index over the Antarctic are influencing grains, natural gas and soft commodities

In the video, I discuss the CLIMATIC VARIABLES that are likely to cause these  commodity-specific events:

  • snows in Kansas, bringing needed moisture to draught-stricken soil
  • important rains for Argentina’s corn and soybean crops 
  • a cold February to many Midwest and (perhaps) eastern U.S. natural gas consumption areas. 


There are additional global teleconnections (other than just a weak La Niña) influencing weather patterns and commodity prices. 

These phenomena are: 

  • 1) Stratospheric warming over the Arctic that will help send the polar vortex back south by February; 
  • 2) A positive AAO (Antarctic Oscillation Index) that will help bring rains to Argentina and southern Brazil within the next few days, but also portends a potential return to February dryness; 
  • 3) Important snows to Kansas wheat later this week and a potential improvement in the Plains drought, come spring.

A Note from our Editor

Our latest issue of Jim Roemer’s Weather Wealth newsletter features the Best Weather Spider which derives an overall score of market sentiment, by ranking seven separate perspectives:

  • 1) Temperature Index
  • 2) Moisture Index
  • 3) Global Crop (for Agricultural Products) or Global Weather-Demand (for Energy)
  • 4) Chart Pattern Recognition and other Technical Analytics
  • 5) Seasonality
  • 6) Economics
  • 7) Anti-Herd Mentality


For example, see the Best Weather Spiders below for corn and coffee. 

  • Will the easing in La Niña result in a much more bearish longer-term Spider for corn as we head into the North American spring and summer?
  • Will we turn bullish natural gas based on our forecast for a cold mid-winter and if so, how do you implement various ETF, futures, and options strategies?
