Atmospheric and Ocean Dynamics May Explain Cycles in Oceanic Oscillations
Seip, Knut Lehre; Grøn, Øyvind (Climate;Volume 7 / Issue 6, Journal article; Peer reviewed, 2019-05-29)What causes cycles in oceanic oscillations, and is there a change in the characteristics of oscillations in around 1950? Characteristics of oceanic cycles and their sources are important for climate predictability. We here ... -
Covariations between the Indian Oceandipole and ENSO: a modeling study
Wang, Hui; Kumar, Arun; Narapusetty, Balachandrudu; Seip, Knut Lehre (Climate Dynamics;November 2019, Volume 53, Issue 9–10, Journal article; Peer reviewed, 2019-07-11)The coevolution of the Indian Ocean dipole (IOD) and El Niño-Southern Oscillation (ENSO) is examined using both observational data and coupled global climate model simulations. The covariability of IOD and ENSO is analyzed ... -
The GDP, the US treasury yield and the federal funds rate: Who follows whom, when and why?
Seip, Knut Lehre; Zhang, Dan (Journal of Financial Economic Policy;, Peer reviewed; Journal article, 2021-06-08)Purpose: This study addresses the fundamental question on how the major players in the economy dynamically interact with each other: among the central bank, the investors in the bond market, and the firms and consumers ... -
A High-Resolution Lead-Lag Analysis of US GDP, Employment, and Unemployment 1977–2021: Okun’s Law and the Puzzle of Jobless Recovery
Seip, Knut Lehre; Zhang, Dan (Economies;Volume 10 / Issue 10, Peer reviewed; Journal article, 2022)Okun’s law is formulated as the ratio between GDP and unemployment (UE): β = f(GDP/UE). It is used to investigate the relations between output and labor input across regions or across business cycles. Based on results by ... -
Maximum Northern Hemisphere warming rates before and after 1880 during the Common Era
Seip, Knut Lehre; Wang, Hui (Theoretical and Applied Climatology;, Peer reviewed; Journal article, 2023)We find that maximal decadal Northern Hemisphere warming increases as rapidly before as after the industrial revolution (0.86 °C decade−1 before 1880 and 0.60–0.68 °C decade−1 after 1880). However, whereas the number of ... -
The North Atlantic oscillations: cycle times for the NAO, the AMO and the AMOC
Seip, Knut Lehre; Grøn, Øyvind; Wang, Hui (Climate;Volume 7, Issue 3, Journal article; Peer reviewed, 2019-03-19)We show that oceanic cycle lengths persist across oceanic cyclic time-series by comparing cycles in series that come from “sister” measurements in the North Atlantic Ocean. These are the North Atlantic oscillation (NAO), ... -
The North Atlantic oscillations: Lead-lag relations for the AMOC, the AMO, and the AMOC. A high-resolution lead-lag analysis
Seip, Knut Lehre; Wang, Hui (Climate;Volume 10 / Issue 5, Peer reviewed; Journal article, 2022-05-05)Several studies examine cycle periods and the interactions between the three major climate modes over the North Atlantic, namely the Atlantic meridional overturning circulation (AMOC), the Atlantic multidecadal oscillation ... -
Scoring Six Detrending Methods on Timing, Lead‑Lag Relations, and Cycle Periods: An Empirical Study of US and UK Recessions 1977–2020
Seip, Knut Lehre; Zhang, Dan (Peer reviewed; Journal article, 2024)This study evaluates six commonly used detrending methods and discuss how detrending may change the timing of events, the identification of lead-lag relations between GDP and employment, and the identification of cycle ...
