Abstract This paper describes the access to, and content, characteristics, potential applications of tropical cyclone (TC) database that is maintained actively developed by China Meteorological Administration, with aim facilitating its use in scientific research operational services. records data relating to all TCs have passed through western North Pacific (WNP) South Sea (SCS) since 1949. TC collection has expanded over recent decades via continuous monitoring using remote sensing...
Galaxy source counts in the infrared provide strong constraints on evolution of bolometric energy output from distant galaxy populations. We present results deep 24 μm imaging Spitzer surveys, which include ≈5 × 104 sources to an 80% completeness ≃60 μJy. The rapidly rise at near-Euclidean rates down 5 mJy, increase with a super-Euclidean rate between 0.4 and 4 converge below ∼0.3 mJy. exceed expectations nonevolving models by factor ≳10 Sν ∼ 0.1 peak differential number corresponds...
We present Spitzer Space Telescope imaging observations at 3.6, 4.5, 5.8, 8.0, and 24 μm of the SCUBA submillimeter sources μJy VLA radio in a 5' × area Lockman Hole East region. Out ∼40 SCUBA/VLA field, counterparts were detected for nearly all except few low-weight detections. show that majority (80%-90%) are cold (i.e., starburst-like) infrared-luminous galaxies (LIR > 1011 L⊙) redshift 0.5 < z 3.5, whose star-formation rate density (SFRD) is comparable to optically selected star-forming galaxies.
We use the source counts measured with Multiband Imaging Photometer for Spitzer (MIPS) at 24, 70, and 160 microns to determine 5-sigma confusion limits due extragalactic sources: 56 micro-Jy, 3.2 40 mJy 70 microns, respectively. also make predictions a number of proposed far infrared missions larger aperture (3.5 10m diameter).
We derive galaxy source counts at 70 and 160 μm using the Multiband Imaging Photometer for Spitzer (MIPS) to map Chandra Deep Field-South (CDF-S) other fields. At μm, our observations extend upward about 2 orders of magnitude in flux density from a threshold 15 mJy, they an order 50 mJy. The are consistent with previous on bright end. Significant evolution is detected faint end both bands, by factors 2-3 over no-evolution models. This agrees well models that indicate most galaxies lie...
Abstract. Smartphone pressure observations have demonstrated significant potential to complement traditional monitoring. However, challenges remain in correcting biases and further leveraging these for practical applications. In this study, we used tropical cyclones (TCs) Lekima 2019, Hagupit 2020 In-fa 2021 as examples conduct bias correction on labeled smartphone data from the Moji Weather app. We propose a quality control procedure utilizing random forest machine learning models. By...
This study investigates the climate trend in intensity change (ΔV) of tropical cyclones (TCs) 24-h before making landfall China during period 1977–2022. Results reveal that ΔV TCs Eastern exhibits no discernible change, while a notable upward is observed for Southern (LTCSC). The LTCSC primarily results from increasing proportion intensifying and decreasing decaying TCs. bimodal pattern proportions further linked to coastward locations lifetime maximum (LMI) LTCSC, along with significant...
As part of the All-Wavelength Extended Groth Strip International Survey (AEGIS), we describe panchromatic characterization an X-ray-luminous active galactic nucleus (AGN) in a merging galaxy at z = 1.15. This object is detected infrared (8, 24, 70, and 160 μm), submillimeter (850 radio wavelengths, from which derive bolometric luminosity Lbol ~ 9 × 1012 L☉. We find that AGN clearly dominates hot dust emission below 40 μm but its total energetic power inferred hard X-rays substantially less...
Dense environments are known to quench star formation in galaxies, but it is still unknown what mechanism(s) directly responsible. In this paper, we study the of galaxies A2029 and compare that Coma, combining indicators at 24 μm, Hα, UV down rates 0.03 M☉ yr−1. We show A2029's star-forming follow same mass–SFR relation as field. The Coma cluster, on other hand, has a population with (SFRs) significantly lower than field relation, indicative process being quenched. Over half these also host...
We investigate extremely red objects (EROs) using near- and mid-infrared observations in five passbands (3.6 to 24 μm) obtained from the Spitzer Space Telescope, deep ground-based R K imaging. The great sensitivity of Infrared Array Camera (IRAC) camera allows us detect 64 EROs (a surface density 2.90 ± 0.36 arcmin-2; [3.6]AB < 23.7) only 12 minutes IRAC exposure time, by means an - [3.6] color cut (analogous traditional cut). A pure infrared detects a somewhat different population may be...
Abstract The wind–pressure relationship (WPR) for tropical cyclones (TCs) in the western North Pacific is reexamined based on aircraft data, TC best track and daily reanalysis data during 1957–87. Minimum sea level pressure (MSLP) was estimated from reconnaissance, maximum surface wind speeds (MSWs) were adjusted speed at flight level. mean MSLP found to be higher 1957–64 than 1965–87, presumably due change reconnaissance instrumentation technology, which results a systematic MSW bias (too...
Based on the best-track dataset from Shanghai Typhoon Institute/China Meteorological Administration, paper provides a comprehensive summary and analysis of tropical cyclone (TC) activities in Western North Pacific (WNP) South China Sea (SCS) for 2022. Using historical climatology 1951 to 2020, anomalous conditions during 2022 TC frequency, origin locations, tracks, intensity, duration entire ocean basin as well landfall events are examined. Results show that overall frequency is slightly...
The effects of dense environments on normal field galaxies are still up for debate despite much study since Abell published his catalog nearby clusters in 1958. There changes color, morphology, and star formation properties when fall into groups clusters, but the specifics how where these modifications occur not fully understood. To look answers, we focused star-forming A2255, an unrelaxed cluster thought to have recently experienced a merger with another or large group. We used Hα, MIPS 24...
Galaxy star formation rates (SFRs) are sensitive to the local environment; for example, high-density regions at cores of dense clusters known suppress formation. It has been suggested that galaxy transformation occurs largely in groups, which intermediate step density between field and cluster environments. In this paper, we use deep MIPS 24 μm observations intermediate-redshift (0.3 ≲ z 0.55) group galaxies from Group Environment Evolution Collaboration (GEEC) subset Second Canadian Network...
Abstract This study investigates interagency discrepancies among best‐track estimates of tropical cyclone (TC) intensity in the western North Pacific, provided by Joint Typhoon Warning Center (JTWC), China Meteorological Administration (CMA), and Regional Specialized (RSMC) Tokyo during 2013 to 2019. The results reveal evident differences maximum wind speed (MSW) estimates, where linear systematic are significant. However, Dvorak parameter (CI) numbers derived from MSWs reported three...
The mean kinematic and thermodynamic structures of tropical cyclones (TCs) making landfall in mainland China are examined by using sounding data from 1998 to 2009. It is found that TC usually accompanied with a decrease low-level wind speed, an expansion the radius strong wind, weakening upper-level warm core, drying mid-tropospheric air. On average, core TCs dissipates 24 h after landfall. height maximum base stable layer both increase increased distance center; however, former always...
ABSTRACT This paper presents a review of tropical cyclone (TC) activity over the western North Pacific in 2013 and examines main factors that influenced pattern activity. The season was characterized by an above-normal genesis number named storms, near-normal total occurrence frequency, accumulated energy. Both SSTs sector East Asian summer monsoon contributed to favorable conditions for active cyclogenesis. circulation also controlled TC track patterns. Three prevailing tracks were...
The trends in annual precipitation and wind induced by tropical cyclones (TCs) over Shanghai during the last 40 years are estimated. Results indicate that there is a significant increasing trend total TCs, which related to positive daily torrential rain days. Meanwhile, decreasing shows maximum sustained wind, seems be downward intensity of TCs when affecting Shanghai. frequencies affected TC translation speed distance from have no obvious tendency. different suggested more comprehensive...
