Looking Back at October 2024 Weather for the U.S. and the World – Posted on November 19, 2024

November 19, 2024Posted inweatherNo Comments

Much of the information in this report comes from the monthly emails I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John Bateman produces a good summary so I use it or most of it. I also add additional information from NCEI or other NOAA websites. At the end of the article, I provide links that will get you to the full reports and much additional information.

 My comments if any are in boxes like this one.

I start with the trends of October 2024 Temperature looking at North America and then the World both land and water and land only. There is a graphic for just CONUS but the format is different and it is not as easy to read.

This is the temperature trend for the month of October in North America. It covers a larger geographical area than just CONUS but I find it easier to read. It looks like the October temperature was a record for the month of October.

The temperature for the world, land and ocean did not hit a new record. But the temperature for October this year and last was a lot higher than the trend.

The temperature for the world, (land only) may have hit a new record but was mostly tied with October of last year. Notice that land temperatures increase faster than land and ocean as water takes more energy.

This month NCEI which is based in North Carolina had a lot of computer problems so the email from John Bateman  is combined  U.S. and World and not as complete as usual.

Looking at the trend for April over time.

This is the temperature trend for April in CONUS.

But look at this the most recent 25 years.  No increase but a decrease.  Data can be misleading if you do not look at it carefully

The temperature for the world, land and water hit a new record.

The temperature for the world, land only also was  a record.

The temperature for the world’s oceans also hit a record. Notice the slope is less. You can see the impact of ENSO in this graphic.

I start with the trends of February Temperature looking at first CONUS, then all of North America and then the World both land and water.

This is the temperature trend for CONUS. There was a decrease for February in 2024 as compared to February in 2023. I show all the data for February starting with 1895.

This is the temperature trend for North America. It covers a larger geographical area but I find it easier to read.

The temperature for the world, land and water hit a new record.

Looking Back at Weather for the U.S. and World in January 2024 Posted on February 20, 2024

I could find the same information and more on the NCEI website but John Bateman produces a good summary so I use it or most of it.

Arctic air mass brought bitter cold and snow to much of the nation in mid-January
Powerful storms brought heavy rainfall and flooding to parts of the southern Plains

                                                                                           February 8, 2024

                                                                                             

                                                                                          Earth had another record-warm month
                                                                                         It was also the second-wettest January on record Contact

I start with the U.S. Key Points

  • The arctic air mass from January 14–18 broke nearly 2,500 daily minimum temperatures county records from the Northwest to the Lower Mississippi Valley.

  • On January 22–25, heavy rainfall brought more than a month’s worth of rain and life-threatening flooding to parts of Texas and Louisiana.

  • January 2024 was the 10th-wettest January on record for the nation, and temperature ranked in the middle third of the historical record for the month.

And then the Global Key Points

  • Temperatures were above average over much of the globe, but the eastern United States, most of Europe and a few other areas were cooler than average.

  • There is a 22% chance that 2024 will be the warmest year in NOAA’s 175-year record and a 79% chance that El Niño will transition to neutral conditions by mid-year.

  • Northern Hemisphere snow cover was near average, but Antarctic sea ice extent was fifth lowest on record for January.

  • Global precipitation was nearly record-high in January, following on the heels of a record-wet December.

I added the below to what John Bateman provided.

 

January 2024 was a busy month

This is the temperature trend for CONUS. There was a decrease for January in 2024

The temperature for the world, land and water hit a new record, but when looking at land alone it was not a new record.

Looking back at 2023 Weather for the World -Posted on January 15, 2024

January 15, 2024Posted inweatherNo Comments

Most of the information in this report comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. The full NCEI report for 2023 can be accessed HERE.

 

 

 

I added the below to what John Bateman provided.

 

2023 was a busy year

 

This is the temperature trend for the world: land and water. There was a big increase in 2923.

 

This is also land and water [corrected previous error) and it is by month and it shows the ENSO state of each month. You can really see that the temperature goes up with the El Nino phase and down with La Nina. It has to do with the releases and absorption of heat by the oceans during the different ENSO Phases. A main reason for that is simple. During La Nina the strong Easterlies along the Pacific skim off the warm surface water is forced into the IndoPacific Warm Pool where it covers a smaller area. When the Easterlies relax during an El Nino the warm water spreads out so the Ocean Surface is warmer. There are other factors also.

 

 

This is just land Globally. It also increased in 2023 but not as much as when including both land and water.

This is for the year but just North America which in not just the U.S. but includes the U.S.   2023 seemed to match but not beat a year about seven years earlier.

 

 

This is December only for North America which includes the U.S. but more than the U.S..  2023 saw a big increase.

This is just the U.S. for December and we have shown this before but you can see that the increase here is less than for North America probably because it does not include Alaska.  I did not include enough graphs to make it easy to figure out but Northern Hemisphere has warmed more than the Southern Hemisphere. It probably has to do with the higher ratio of land to water in the Northern Hemisphere.  When water warms it is not just at the surface so the impact of Global Warming on the surface of water is less than the impact on the surface of land.

Looking Back at the weather for the full Year of 2023 in the U.S. Posted January 10, 2024

January 10, 2024Posted inweatherNo Comments

Most of the information in this report comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. John Bateman sends me two emails. One on the World situation and one for the U.S.

I probably should have addressed the single month of December before the full year of 2023 but I received this email today so I thought I would write the article tonight for Wednesday viewing.

This article is about the full year of 2023 in the U.S.

This is the U.S. Annual temperature trend. 2023 was by no means a record but it was above the trend line. +0.16F a decade is a fairly steep slope.   You can see some cyclical characteristics in the data but the trend is clear. If I calculated the trend since 1970, the slope would be quite a bit steeper.

Now I will present the information provided by John Bateman with perhaps three additional graphics. Some readers may need to click on “Read More” to access the full article. It is how the Home Page can display the introduction to many articles.

Looking back at November for the World December 19, 2023 – Earth had its Warmest November Ever Since Reliable Data has been Available.

December 19, 2023Posted inweatherNo Comments

Most of the information in this report comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. The full NCEI report for November can be accessed HERE.

I added the below to what John Bateman provided.

This November saw a huge jump. Remember this is the data for both land and water.

This looks just at land but the trend is similar.  In fact the regression line is even steeper.

 

This is just North America. It is more than just the U.S.  and the slope of the regression line is even steeper. But for North America, unlike the world, November did not set a new record.

This shows selected anomalies but it mostly covers temperature around the world.

Assessing the U.S. Climate in November 2023 – December 13, 2023

December 13, 2023Posted inClimate, weatherNo Comments

Much of the information in this article comes from the monthly email I receive from John Bateman. He does public outreach for NOAA and in particular NCEI. I could find the same information and more on the NCEI website but John produces a good summary so I use it or most of it. I also sometimes add additional information from NCEI or other NOAA websites. John Bateman sends me two emails. One on the World situation and one for the U.S. One of the things I like to add to what John Bateman sends me is the state ranking maps. These maps show how temperature and precipitation for each state rank relative to the 129 years of what is considered to be the most reliable data we have.

This article is about November 2023 in the U.S.

This trend analysis comes from Climate at a Glance also from NCEI

This is the U.S.  November temperature trend.  This past November was by no means a record but it was above the trend line. It was a relief in a way as some recent months have been much above trend and record breakers so the factors that were causing that may have been short-term but in any event did not show up this November.  I will compare this to the world trend in a future article.

Now I will present the information provided by John Bateman with one additional graphic also from NCEI plus the state ranking maps.

This is the U.S.  October temperature trend.  This past October was by no means a record but it was above the trend line. It was a relief in a way as recent months have been much above trend and record breakers so the factors that were causing that may have been short-term but in any event did not show up this October.  I am unable to compare this to the world trend as it is not yet available but will be soon.

Now I will present the information provided by John Bateman with perhaps one additional graphic also from NCEI.
