Sentences with phrase «phase cycle variations»

«But when we consider that phase cycle variations can be up to 100,000 times fainter than the host star, these detections become truly astonishing.»

Not exact matches

An artist's rendering of an exoplanet with cloudy mornings and clear, scorching afternoons, exhibiting a cycle of phase variations that occur as different portions of the planet are illuminated by its star, as seen from Earth.

Astronomers at the University of Toronto, York University and Queen's University Belfast used measurements of the phase variations of six exoplanets obtained by the Kepler space telescope to forecast their daily weather cycle.

Even though the length of a woman's menstrual cycle can vary from cycle to cycle, the variation occurs during the period of time before ovulation (the pre-ovulatory or folicular phase of the menstrual cycle).

There are two variations, one for Phase I and the other for Phase II of the menstrual cycle.

Carb cycling diets are common as fat loss tools, so it would be interesting to see if it is really the phases corresponding to best nutrient utilization, or simply the variation in the diet.

CO2 concentrations are meaningless — it's water in all it's phases reacting to variations in solar irradiance brought on by various solar cycles and orbital cycles that controls climate — PERIOD!

The solar application offers the potential for the long - range prediction of SOI behavior and associated rainfall variations, since quasi-periodicity in solar activity results in an expected cycle of situations and phases that are not random events.

Since nothing is happening beyond normal variation in the climate or weather, not even trends (with 1000 year plus cycles a short phase will look like a trend), then there is no measurable basis for claiming CO2 is changing the climate.

However, although the latter varies significantly from cycle to cycle (as reflected in different cycle magnitudes varying by a factor of 2), the tilt angle exhibits roughly the same variations over all cycles, in accord with the idea of a regular cyclic behaviour (Suess et al. 1993; Cliver & Ling 2001; Alanko - Huotari et al. 2007), depending only on the solar cycle phase and not on its strength.

The basic arguments against the existence of such a relationship are that variations in climatic parameters do not always occur synchronously with the corresponding 11 - and 22 - year solar cycles: the phase shift between climatic and solar variations is inconstant and changes with time from 0 ° to 180 °.

During the descending phase, the tilt angle fluctuates essentially, and these variations differ from cycle to cycle.

Amplitudes, rates, periodicities and causes of temperature variations in the past 2485 years and future trends over the central - eastern Tibetan Plateau Chinese Science Bulletin Oct. 2001 with a forecast - temperature decrease 2006 - 2060... The «trending up» is a consequence of the phase of the longer «1000 years» and «210 years» cycles, with n assumed maximum over 2000 - 2020.

Yet variations of up to 0.2 C occur in phase with the solar cycle.

It also gives us a degree of seperateness / independence between ocean and solar cycling that goes a long way to explaining the correlation problems which would then most likely arise from phasing differences between solar and oceanic variations.

The only use of controversial was in this sentence from AR4: «an empirical association of cloud cover variations during 1984 to 1990 and the solar cycle remains controversial because of uncertainties about the reality of the decadal signal itself, the phasing or anti-phasing with solar activity, and its separate dependence for low, middle and high clouds.»
