Global climate report for March 2022

Earlier this week, NOAA National Centers for Environmental Information (NCEI) released the monthly global climate summary for March 2022. Here are a few highlights.

The March 2022 global surface temperature departure was the fifth highest for March in the 143-year record at 0.95 °C (1.71 °F) above the 20th-century average. This was also the highest monthly temperature departure since November 2020. The seven warmest Marches have occurred since 2015, while the 10 warmest Marches have occurred since 2002. March 2022 also marked the 46th consecutive March and the 447th consecutive month with temperatures, at least nominally, above the 20th-century average.

Global surface temperature compared to the 20th-century average each March from 1880 through 2022. Cooler-than-average Marches are colored blue; warmer-than-average Marches are red. March temperatures have warmed by 1.53 degrees Fahrenheit (0.85 degrees Celsius) per century. The last time Earth had a cooler-than-average March was 1976.

The month of March was characterized by warmer-than-average conditions across much of Australia, southern and eastern Asia, and parts of Central America and northern South America, central Africa, as well as parts of the Atlantic, Indian, and northern and western Pacific oceans. Record-warm March temperatures were observed in southern Asia, and parts of north and western Pacific Ocean, as well as parts of the Atlantic Ocean. Overall, the record-warm March temperatures encompassed above 5.5% of the world's surface—the sixth-highest percentage for record-high March temperatures.

Meanwhile, near- to cooler-than-average March temperatures were present across parts of central North America, southern South America, southeastern Europe, the northern Middle East, western and central Russia, as well as parts of northern Atlantic, and the central and eastern tropical and southeastern Pacific oceans. However, no land or ocean areas had record-cold March temperatures.

As has been the case for much of the last year and more, the lower-than-normal SSTs [sea surface temperatures] of the central Pacific associated with the La Niña phase of the ENSO phenomenon dominate the Pacific Ocean anomaly pattern, but with some subtle shifts this month. Across the tropical Pacific the negative anomalies for this March are very strong and expansive and roughly in the same place as in the composite (the mean pattern of a number of La Niñas in March). But, distinct in this year's March, a narrow positive anomaly just north of the Equator sweeps across the ocean into South America. This feature is not in the composite, is a change from last month (February), and may indicate some coming change in the ENSO system.

The report also noted the dry conditions in the United States:

The western U.S. and Mexico remain in a strong drought and the general precipitation deficits across the region for March did not help alleviate the condition. The area of recent dryness extends eastward through the Gulf of Mexico. This general pattern matches roughly that in the La Niña composite, including offshore west of California and Mexico. La Niña is well known for being related to dryness over the southwest U.S. Wildfires in Texas were related to the dry conditions.
