This study investigated variability and trends in the annual snow cover cycle in regions covering high latitude and high elevation land areas in the Northern Hemisphere. The annual snow cover cycle was examined with respect to the week of the last observed snow cover in spring (WLS), the week of the first observed snow cover autumn (WFS), and the duration of the snow-free period (DSF). The anal...

Acoustic signals transmitted from the ATOC source on Pioneer Seamount off the coast of California have been received at various sites around the Pacific Basin since January 1996. We describe data obtained using bottom-mounted receivers, including U.S. Navy Sound Surveilance System arrays, at ranges up to 5 Mm from the Pioneer Seamount source. Stable identifiable ray arrivals are observed in sev...

2 Annual and quarterly data on German GDP are decomposed into a nonstationary trend, a stationary cycle and a seasonal component using Kalman filtering and smoothing techniques. The computed trend components of the unobserved component models are then used to calculate annual and quarterly output gap measures for the German economy.

The objective was to characterize female germ cell renewal during the annual reproductive cycle in two species of ostariophysian fish with distinct reproductive strategies: a siluriform, Pimelodus maculatus, in which oocyte development is group synchronous and the annual reproductive period is short; and a characiform, Serrasalmus maculatus, with asynchronous oocyte development and a prolonged ...

 An order-of magnitude estimate of life-cycle GHG reductions across potential municipal solid waste management scenarios shows that achievable reductions are on the order of current annual emissions from the conventional waste sector quantified in OECD countries’ GHG inventories. In other words, in most countries, at least 4 percent of current annual GHG emissions could be mitigated if waste m...

Vegetation has closer relationship with the hydrological cycle, changing them due to their conditions. Vegetation regulates the hydrological cycle making water faces all the stages adequately causing the process stability. Vegetation retains great parcel of the rainwater, freeing it for the water courses and surface and subterranean reservoirs, little by little. In this work, the impact of defo...

The El Niño-Southern Oscillation (ENSO) phenomenon, the most pronounced feature of internally generated climate variability, occurs on interannual timescales and impacts the global climate system through an interaction with the annual cycle. The tight coupling between ENSO and the annual cycle is particularly pronounced over the tropical Western Pacific. Here we show that this nonlinear interac...
